[00:00:01]Namaskar, good afternoon.

[00:00:07]Our chemistry second class today.

[00:00:41]I want to say which of the following is an amorphous solid. Good again. Here we go.

[00:00:47]Amorphous solid going to quiz it.

[00:00:50]What's a rubber, graphite, salt? Going to over by the number being and the number being cotton.

[00:00:57]What are the top?

[00:00:59]What is the correct answer I say rubber?

[00:01:01]Rubber is the number being cotton.

[00:01:04]Good guess it.

[00:01:05]Rubber. Next I saw for all going to get a copper for a moment and come here.

[00:01:09]Come on. At the for all going to get a copper for all going to get a copper for all going to get a copper for a moment and come here. The number of atom in a simple cubic unit cell is going to over by the copper.

[00:01:20]Going to get a copper for a moment.

[00:01:23]I was in the answer to the bar.

[00:01:25]What?

[00:01:30]Yeah, I got to answer to the bar for a moment and come here at the for all going to get a copper for all going to get a copper for a moment and come here.

[00:01:35]Option A correct answer. Good guess it.

[00:01:37]One.

[00:01:39]Next I saw sporty cut short key going to get a copper for a moment and come here. Good guess it. Sporty defect is observed in crystals when I got to get a copper for a What?

[00:01:53]Sporty cut short key going to get a copper for a moment and come here. What?

[00:01:59]Density increase in unequal number of cations and atoms are missing. Equal number of cations and anyone are missing.

[00:02:16]Which type of solid is diamond? Here I can have no good in product.

[00:02:42]Option B.

[00:02:45]Next I saw the coordination number of body centered cubic this is structure.

[00:03:16]Correct answer.

[00:03:17]This Next I saw which of the following is a ferromagnetic substance.

[00:03:38]Correct answer I saw the one CRO2 option CRO2.

[00:03:42]Okay, so next I saw the packing efficiency of a face centered cubic unit cell.

[00:04:01]>> Correct answer is 74% Next I saw zinc blend structure has coordination number.

[00:04:23]Correct answer is 4:4. Option A will be correct answer.

[00:04:28]Next I saw P-type semiconductor is formed when SI is defined SI is doped with Which of the following is a network solid?

[00:04:56]I am going to say the answer.

[00:04:57]Graphite, ice, iodine, sucrose.

[00:05:30]The percentage of empty space in body center >> body centered cubic Correct answer? 32% So, the percentage of empty space in body centered cubic So, next question Cations are present in the interstitial site Only 299.

[00:07:08]So, this is seriously Take a sec.

[00:07:14]So, remember the next question to answer.

[00:07:22]To get an N-type semiconductor, the impurity added to silicon should have Five does it have electron to give or take away? Five Option C will be correct answer.

[00:07:53]Next I saw the total number of Bravais lattice.

[00:07:59]What do you call it? 14 correct answer.

[00:08:03]14.

[00:08:05]Which substance show both Schottky and Frenkel defect?

[00:08:11]Frenkel do it a bit complicated to take away.

[00:08:13]What do you call it? NaCl.

[00:08:16]So, correct answer was it AgBr. AgBr AgBr here it will chemical name.

[00:08:27]Next I saw hexa hexagonal close packing has a coordination number.

[00:08:38]human Skipper Correct answer was it option C. 12. Take this option C about correct answer.

[00:09:17]Next I saw an example of a polar molecule solid is Correct answer was it the mark SO2.

[00:09:35]Next I saw the appearance of color in alkali metal halides is generally due to Next I saw which of the following is a pseudo solid?

[00:10:09]In a face centered cubic lattice, an atom at the face center is shared by Next I saw the relation between edge length A and radius R for a simple cubic cell is A equal to R. Option A will be the correct answer.

[00:10:53]Next I saw which of the following is an ionic solid? Below are the ionic solids.

[00:11:06]Paramagnetic substances The correct answer is the option B will be the correct answer. Weakly attracted by magnetic field.

[00:11:25]The empty space in a hexagonal hexagonal close packed structure is going to give HCP got her a quality that for my income.

[00:11:37]Correct answer, 26%.

[00:11:40]Next I see which of the following is a molecular solid total atomic cotton.

[00:11:47]Atomic cotton is a tomorrow argon. Okay, guys, next I see the number of tetrahedral fights in a unit cell of FCC structure is FCC Apple core at 200 to follow the total standard of the one.

[00:12:32]Here we are fine.

[00:12:42]FCC Apple core at a total 200 to follow the total standard of the one eight correct. Next I see graphite is a good conductor of electricity due to the presence of your opposite of a graphite video to put it on your opposite of a video to put it on your opposite of a video to put it on your opposite of a video to put it on your opposite of a video to put it on your opposite of a video to put it on The unit cell with dimension A is 30 B is not equal C and alpha equal beta Okay, so here we are fine.

[00:13:15]Come on here.

[00:13:17]So this one here orthorhombic monoclinic here we are fine.

[00:13:38]>> I can say it was option C.

[00:15:31]Next question for a BCC unit cell the relation between A and R is R equal root three by four bracket A.

[00:15:46]You can say Next I saw an example of a nonpolar molecule solid What do you call S2O correct answer is CCl4?

[00:16:03]So I'm live class I saw a person.

[00:16:06]My life class is Saturday night.

[00:16:30]Correct answer I mean next I saw a solid having no different service for me to call you to give a call.

[00:16:39]What do you call correct answer what do you call correct answer what do you call?

[00:16:43]Done I mean by M4 I am a first call.

[00:16:48]I don't I saw tropic what do you call B or C what do you call correct answer next I saw The number of atom in a body centered cubic BCC unit cell is Correct answer is A.

[00:17:07]Option B two you can say next I saw more details I don't know what do you call correct answer I don't know what do you call correct answer I don't know what do you call correct answer you can it? Next I saw tension metal and their compounds so on common that too option they have a guy can say all of this.

[00:17:34]Next I saw in which of the following pairs is the coordination number that same color going to I saw that they do say that my C P R C C P Correct?

[00:17:47]Next I saw all going to get a couple of going to go to that one more than 68% 52.4% Next I saw which of the following is an example of a military solid going to go to that one going to go to that one going to go to that one option A C U Next I saw crystal so and it's trophy because of regular arrangement of particle going to go to that one going to go to that Next I saw that in itself of calcium chloride today I saw cesium chloride cesium chloride I am going to go to that one going to go to that one B C C Okay? Next I saw all going to go to that one all going to go to that one which of the following is a diamagnetic substance going to go to that one C 6 8 6 benzene The self melting point of crystalline solid is due to going to go to that one going to go to that one long range order How many units are there in one mole of a simple cubic lattice?

[00:19:01]Going to go to that one going to go to that one option A going to go to that one 6.022 into 10 to the power 23 Dry ice is an example of going to go to that one going to go to that one going to go to that one molecular solid going to go to that one You get it? graphite hexa ognel So yeah, I was saying that the important question about chemistry chapter two part So you have to do class two chemistry, physics, biology to get any class or a mark. important common question B fun D form of I am a mock test or time to my Saturday mock test of for you guys
