[00:00:00]now the next question arises here okay we came to know about organic chemistry we came to know the source and the history of the organic compounds or C now the next question arises why do we require a new branch of chemistry that's organic chemistry because already are having existing - that is physical chemistry and your answer in organic chemistry when you require a new branch of chemistry that said said to be has organic chemistry which you are remaining today the reason is there are huge differences large differences alright between the organic and the inorganic compounds when inorganic compounds is merely ninety thousand and organic of course you know how much this it is more than five millions more than five million that is more than 50 lakhs of organic compounds out of that ninety percent is artificially prepared in the lab it is artificially synthesized ninety percent more than ninety percent of it the compound all right so hence where inorganic compounds are merely ninety thousand organic compounds are more than 50 lakhs modified millions and every day some are other compound is being added to the list the first point is that it is large number organic compound are of large number huge so we can say that the mother of the science not chemistry is a matter of science is your organic chemistry got it without the knowledge of organic chemistry it's not possible science is not possible today its life is not possible it's very simple I can select today see I am teaching to you online isn't it how by the help of mobile our of net analysis what is the handset of mobile made of polymers plastics organic chemistry is the branch of organic chemistry your laptop your desktop or it the screen the laptop screen or the cabinet of the laptop or the desktop what you sped up off again same thing polymers plastic organic chemistry correct you wake up in the morning the first thing buddy do is done you brush your eat isn't it you use the toothbrush what is that that is nothing but a game plastic polymers organic chemistry after that you take your different let us say you are taking that is your bread you are taking jams jellies butter and all these things bread is made up of what east we are adding east to the flow they are ready is dissolved again the organic uh found in the Giants the recent butter appear added that is sodium Pennzoil which acts as a preservative organic compound the clothes which are very mean mostly they are the synthetic clothes begin organic compounds so you go on making the list right from the morning to the end of the day you see the knowledge of organic chemistry is being used in one way or the other the house is filled with alpha pod cements again organic chemistry pages being used nowadays you know that we are using the red oxide reduction is hard again it's an organic about it is a knowledge of organic chemistry all right sir in this way in one way or the other organic chemistry is used in your day-to-day life without that it's not possible it is not at all possible we can select life is not possible now the log dog is not at all possible all right for that particular purpose organic chemistry is large number compared to inorganic of course we can select first part say second part aside they are complex in nature organic Kapow complex even if organic compounds basically consist of carbon and hydrogen and few other elements are attached to it like oxygen nitrogen sulphur phosphorous and other things but still then organic about the complex in nature they're not simple like in organic compounds like sodium chloride like in sodium sulfate potassium nitrate ammonium chloride and they are very simple compounds all right they have got simple the thirds of repentance but you find now here you see when you study the preparation of organic compounds like alkane alkane alkane alcohol idea ketone sisters correct carboxylic acids and so many you be studying it you will be seeing that it has got a complex method at different methods of propulsion it's not a simple method so hence it is complex in nature sorry now next is after that you find out that mostly they are covalent molecule which are organic of course most beautiful most we were all a covalent molecule but there are many compounds maybe I like maybe cold sodium chloride is that I come out but carbon dioxide is covalent yeah one more question comes here the carbon dioxide is also a compound of what you can say of Cardinal like carbon dioxide calcium carbonate then you can say whatever the more we can have calcium bicarbonate yeah so they are what is considered to be as an inorganic compounds why not organic because even if carbon is present as one of the constituent element in carbon dioxide carbon monoxide calcium bicarbonate or calcium carbonate he very carbon is being present but their behavior their nature their properties is completely different from organic about hence they are not included in the branch of organic chemistry even if carbon is one of the constituent they they are included in organic chemistry alright so organic compounds are mostly covalent in nature there are not at all there : they are being formed the organic compounds are formed by the not that grunts but with the sharing of electron pairs we can say that okay more of the bond about you will be strain it in the body in chapter next is after that this suppose have low melting and boiling point low melting and boiling point because covalent compounds in general liquids and gases there's in liquids and gases and organic compounds opposed to liquids and gases and hence they have got low melting and boiling point for that particular purpose because it matches with the properties of the covalent compound enhancement i only compound they are joined together by strong electrostatic force of attraction ionic compounds so hence therefore - ting and Burleigh point sodium chloride sodium ions and chloride ions I had together the strong electrostatic force of attractions hence they have got high melting and boiling point but organic about know they are met together by covalent bonds correct hence they are normally taken by the point and exact reason only as there : they are insoluble in water or I should say for our solvent water is you know that it is a polar solvent what reefs por nada means work but if you get the word polar pull average which has two words positive poles and negative poles a hydrogen HOH is right water can be written in this way in organic chemistry you see hydrating water there George lot of things you learn it now lot of things it is written as it shows when H is positive and which is negative that's it sensor this polar big answer that the one the compound which has which has got poles even if it is coverage but it is having positive a negative poles so hence it is a few people are so handsome water is considered to me as I put our opener not only this much Pilar means it not me this just an easy language I'm explaining many will be saying about the polar compounds you will be seeing that a lot of the more things will be coming all right lot of more concept you will be saying about it so just an easy language what are you a layman if I may want to make you understand that what is polar that is what I said Paula Deen's hola means to ports fur coats pasta person reports how see I am sorry to you all right why what I said it is in soluble in water but soluble a organic solvent organic compounds are soluble in organic solvent organic solvents are nonpolar in nature which one is organic solvent diesel petrol kerosene alcohol benzene Charlie they are said to be as organic solvents chlorophyll correct so they are organic solvent in organic solvents they are in sulfur which one there is organic compounds because that clear next is what do you find is that this show I'll so many some just come to I give the example I so mister organic of course this phenomena we don't have any neurotic of course we don't have got it for example see here one more example I assume it is amended let me are having a molecule of the c2h6o isn't it C 2 X X so it can be written as c2h5oh it can also be written as ch3 ch3 C c2h6o we also see two and six o so it is what it is it high alcohol it is an alcohol how do we come to know from this functional broken sewage and this is what this is ether but her tiny tiny ether the I retired because to be kind is there dimethyl ether the function to be single bond o single God whose functional group dishonest ether now using a word here functional group next is also the same thing this functional group properties functional group properties you will find only which top out organic apart have any functional group in you know any couples a visa didn't have any compound be written in this way for example x2 support can I write in any other way so that it will be two different compounds like here C 2 X 600 I arranged in two different manners it has got two different structure we can say that this is a modular form less and if this is a molecular form and these two are the structural formula they have put two different structures now it's useful for can arrange in two different structures and it can I arranged in two different subject potassium nitrate can I do it in two different structures ammonium chloride can I do in two different structures no not at all not possible because they're inorganic compounds they do not so the phenomena also very self but organic about thus you are having a chapter on isomers and I so very simply be staying here only in class level and that you know that how different types of isomers I am having it so organic compounds also phenomenal benefice organism in our geta compound is not functional group properties this is function rule which determines the chemical properties of the compound how do you know it is alcohol because from the functional to the voyage from the functional group that is which functional group determined same chemical properties of the compound which is the characteristics phenomena of organic compounds only we don't find functional group it in organic compounds in your also say in the function due to single bond do single bond alright in this way what do you find is that they are poor conductor of heat and let's it is not correct because they they are not soluble in water they are not soluble in water they do not dissociate into ions so how we will conduct heat and how they will contact communities it all right so in this way what do you find inside they are they are showing the molecular reactions if you see the chemical there's only molecular reactions they also show the phenomena of catenation or a catenation aggregation what I said catenation this so the phenomena Venus for many other we can write so many points it's not just seven eight nine ten points we can write so many parts so catenation activation is a unique property of carbonator to combine with itself and also with other elements to form a long chain of cops they can repeat catenation is the unique property of the power of an atom it's a unique property of the calculator to combine with itself like one can combine with carbon so many other cargo all right - it can combine in this way it's a unique property of the carbon atom combined with itself and also with other elements like in between even see oxygen is coming with other elements like oxygen it can come in between sulphur you can have nitrogen in kappa alright so again I repeat catenation is the unique property of the carpenter only further gravel or a carbon atom shows why I'll come to it later it's a unique property of the carbon atom to combine with itself and also with other elements like oxygen hydrogen sulfur chlorine in this way to form a long chain of compounds or a branch compounds unless what you can say cancellation this is known as captivation it's the peculiar phenomena is a peculiar characteristics of the carbon atom becomes aware so all these particular thing you can find it already talk or do you find it you know reading accounts of the scenes no so these different sheets organic to inorganic compounds and how can you keep the inorganic compounds in the branch of organic or how can you keep the organic in the branch of inorganic because there's completely different set of properties completely began so that so hence we require a new branch of chemistry organic chemistry or you may come in here exam so what is the fans of inorganic organic chemistry you can read these parts because that thank you very much
