Nomenclature part 25

Added: 2026-05-12

[00:00:00]now the next rule is that if the genie as well as the ring contains same function both are having the same function Chinese also having the same function the brain is also having the same function in that case already say you decide according to the number of carbon atoms suppose the chain contains six carbon and the ring contains five carbons that the chain is the root word and the ring is your profits understood now if the chain and the ring contains the same functional group in that case how do we decide if we decide on the basis of the number of carbon atoms in the chain as well as in the ring so if the team contains six carbon and listen carefully and the ring contains five carbon atoms then the chain is your root word and the ring is your perfect now you may ask me searching array both contain same function group both contain same number of carbon atoms fine then in that case we will see the position we'll see that in the chain which position the functional group is there and the rain which position the function group is there whichever is having the worst position that will get the preference now you will say sir both are having the same positions fine in that case in that case we will see the prefix is there or not we will see the prefix it is there or not so accordingly we will decide so somewhere or other it is going to break so if the prefix is there then the prefix will decide in which case that prefix is in the rain terrific skills the lowest number when the beam will become the function sorry ring will become the root good if the chain contains the prefix and that gets the lowest number compared to the ring then the chain becomes the but it can say function every can say the root let me take an example that it will be clear to you okay let me take an example suppose we are having here five carbons okay we are having here Oh H let us see we are having here there is a ring which also contains five carbon array and it also contains Oh H clear now you can see it here that I have put the if I count from this and definitely I come from the center of it if I am taking the chain then what you find is that that the it contains the second calculator and if I count from this send if I start counting because that I need to come from here then because branching starts from here so one two it's also gives a second position okay both are same now what we might have like to be sad here I will put that is nothing but yeah I will put it that is bromo I put it here sorry yeah I put it as bromo and here I putting it as clear here I'll be putting it as let us say and putting it here bro on here now let us see what it covers okay now it is ch3 now it is satisfied here ch2 and here it is see a chair it is ch3 done okay now let us see which becomes the root word see here which second position arrows words second position here from O one two three four code portion because definitely have to give the Rose number 2 the function group definitely count it as would answer this I don't say talking will do from this side don't say it out so here second position we start the content support question to get the pro in the chain in the ring will come from this egg one two three four five so bromo comes in the fifth portion you may have said here it is they come off then what we'll do anything anybody can take us that long is chain and we can do it in that case all right I said anyone in that case what will happen if the ring and the chain contains the Mac same number of carbon atoms what I said in the previous rules that ring will get that reference so who wins the race the ring will be in the race ultimately if bromo is being presented all righty brewers we present here here also 40 rows of four one two three four it promotes we present here then the green and the chain contains the same number of carbon atoms so in that case I told you the rule if both are having the same number of carbon atoms that the ring will be given the preference not that chain understood not anyone we can take it just just simply I say to that particular one okay yeah so here I mean it has grown by rubbing it I put it over here now let's name it name is particular okay now let us name it so one two three four and five so what do you get it is here secondary prefects you write it think of and write it properly for growing fourth question you can see provided for growers report question pro here one two three four and five may get it but it will not count in this way one two three four five no in that is which will become the highest number which is because of HN bro this is function group is always to give than us remember it so for bromo now in the fourth question itself this complex group starts for it what is that complex in fifth position bromo alphabetical order after eight because both are prefix now both are prophets it something both things are prefix isn't it you know this is a root word means it whole thing is a perfect whole thing DISA perfect this is perfect but this is a buncha you don't remember it so now hear what i said five bromo alphabetical order first 5 promo then what is that - hydroxy - hydroxy then what is that cyclo penta cyclo pentene for Rojo all right foot potion bromo then 4th position but if ID is that feet potion Bravo is there and second portion Hydrox is there - hydroxy cyclo penta / 2nd the prefix now primary prefix already gone inside now root world root word is what it contains five carbon atoms so it is spent primarily suffixes for primary suffixes a we can say and say n3 suffixes of our second recipe kisses to all so II and whoa both bubbles do not believe he will be mentioned so for bromo 4 then 5 promo - hydroxy cyclic and I went on to odd because the IV's way all right enough next after that the next rule if suppose an ally cyclic array is attached to an aromatic rainy then which will be the root world in that case the aromatic ring becomes the root word because it contains the lower degree of hydrogenation 1 suppose we are having here C R that is this one is there this one is our C 6 H 2 because six seven one two three four five six six seven Israel so it contains the 6 H 12 when it is attached an aromatic ring aromatic ring what is the formula benzene c6h6 then what I said which is a root word root what is your automatically what it why do the lower degree of hydrogenation it contains six hydrogen atoms it contains two old metal atoms so in that case what if an is that ring is the root word and change is here sorry this aromatic ring is the root word and any cyclic ring is your Perfect's correct so remember it if an ally cyclic ring is attached to an aromatic ring then a cyclic ring is the prefix and aromatic ring is the root word so what is the name of this compound the name of this compound is secondary prefix is cyclo exile because this is your cyclohexane one hydrogen is no from here so from exile you everyone hide it and it becomes Xie you know it alakina free overhead it becomes Alki e so cyclonic sign so this is your cyclonic side and what is this this is nothing but it is your root word is benzene nothing else is there so slightly inside let's see the name of the goddess suppose we are having industry Tuesday both are cycling style then what is the name one is your products what is the root word so it is nothing but cyclohexyl cyclo hexane cyclohexane cyclohexane because of that one is your profits another visio root word cyclohexane cyclohexane now the last room we can say last rule is that we want to discuss this particular rule in aliphatic that suppose we are having a psychic dream I do the helicity green we are having a functional again switch and the functional group contains a carbon atom attached to it listen tell me we are having a cycle you can recycle green contains a function contains a carbon atom attached to it as you can see to it let us say we are having an alley cyclic ring and every cycle it will contains a functional let us say yes I'm having another cyclic ring and it contains a functional group attached to it and the function group contains a carburetor now in this case what you have learned is that the carbon atom of the functional group is not included in the group word you can see it is not included this cognitive this cognitive this calculator it's not including the roto-rooter is what route what is cyclohexane here hoot what is cyclohexane because it's outside the ring how do we inside it is not inside the ring so I'm said there in this particular one so how can we take this carbon atom inside the room hood will not count in this manner one two three four five six seven Millikan is this a is if the ring one is outside but it need not come to this way one two three four five six seven now it's out literally so it is not included in the root word and the naming is done differently I have told you or is not differently the name will be this is carbon I tried instead of nitride this will be carboxylic acid instead of Koyuk acid this will be carve aldehyde instead of and I've given you a chapels for this particular purpose in the aliphatic go through it alright so what is now my username brother who got the rule but I said he found a lease act III needed attached to a functional group and the functional group contains carbonate and presented it listen carefully that the carbon atom of the functional group is not included in the root word it is not included outside the range that is not included so hence this they noticed about a cyclo hexane this one is cyclohexane whoa night try cyclohexane part when I tried this is cyclo pentene Taliban behind this is car body hey this is cyclo hexane carboxylic carboxylic sail cyclohexane carboxylic acid because of the naming is done in this particular manner alright so listen the Sun if suppose any prefix is there let us say you have any time you believe so you say we tie the numbering you do want to do so to methylcyclohexane and what I try in this anything you have to do it according you have to do so these are the rules for writing the IP settings for exactly compounds I have completed thank you very much
