Sir cyclo alkane also shows G.I then why not include that too as a sysyem in the last qeustion?13:46 And we also get mirror images which are non superimposible for some ring compounds,What about them?
In 6th question, the optical rotation of 1st cmpd is zero where as for 2nd cmpd is not equal to zero ,but for cmpds to be optical isomers the optical rotation should be +α and -α
2:31 shouldn't the answer be 8.....like ring also shows GI so and cis configuration means .....either both groups are lying below the plane or both above the plane that means 2 possibility....and 4 possibility cis and trans of two alkenes .........answwr should be 2×4=8 ????
Sir what is difference between compound having optical activity and having optical isomers. I don't understood how optically inactive compounds can shows optical isomers. Please reply...
i m trying to answer it.. hope it explains.. concept is diastereomers are pair of stereoisomers .. that means the pair has to be stereoisomer of each other.. meaning their structure and molecular formula should be same.. only the orientation in space should be different! Since relative position of atoms in changed.. we cant call them diastereoisomers.
no yeh steriomer hi nahi hai toh I guess OI Ka sawal hi nhi hota bcoz d iasteriomers are those compounds which have same structure but are not mirror images of each other yaha structure hi same nhi hai
In the video of challenging problems of stereoisomerism , in the 7th question the structures are also diastereomers but the answer was only structural isomers
Ok.... when You try to rotate them nd u will get not the exact same or identical compound because symmetry is passes through benzene's center And When u rotate TT u will get the TT as well As well as CC too They are fully different
Sir what was your rank in your first attempt?As you qualified in your drop year with a very good rank...Telling us about it would be very motivating for us.
Any Time Padhai Academy Wow..Sir..You couldn't qualify in the first time and in your second attempt you nailed it.Thanks for motivating me.Im already preparing with full force..This just gave me an extra boost!
Double Bond Equivalent or Degree Of Unsaturation DOU/DBE = (C+1) - {(H+X-N)/2} where C is number of Carbon, H is number of Hydrogen, X is number of Halogens and N is number of Nitrogen.
Sir please upload more and more videos of the same kind like this one. God bless you sir!

Sir,are compounds in question 6 at 10:34 diastereomers?As they are not mirror images of each other.
2:31 shouldn't the answer be 8.....like ring also shows GI so and cis configuration means .....either both groups are lying below the plane or both above the plane that means 2 possibility....and 4 possibility cis and trans of two alkenes .........answwr should be 2×4=8 ????
Yes sir,same doubt...the ring can also show GI so the answer must be 8..
Sir plz reply🙏
sir in question 3 how you can change the position of F,CLBr,I although we know that around pi bond rotation is restricted
Sir what is difference between compound having optical activity and having optical isomers. I don't understood how optically inactive compounds can shows optical isomers. Please reply...
Sir at 13:38 par 2 chiral centre wale compound main GI bhi hoga na ?
thanks sir I have learn most important concepts form this video please make more vedios.
Q1 me Jo groups attach hai cyclohexane se unke carbon ke about GI bhi toh ho skta h . . .
Sir i get toomuch help . Thank you sir. Always keep on helping us
Sir In the very first question ring ke respect me GI hona chahiye ??? Please explain
at 11:43 will the compound not be diastereomers bcoz in 1st(2S,3R) while in 2nd (2S,3S) is present????

Shubham Mittal nice explain thankyou
very good explanation , sir please upload short tricks fir physics and inorganic reactions
Sir in question 7 it can also be distereomer as it satisfies the condition.
Optically active compound which are not mirror image of each other
no yeh steriomer hi nahi hai toh I guess OI Ka sawal hi nhi hota bcoz d iasteriomers are those compounds which have same structure but are not mirror images of each other yaha structure hi same nhi hai
thanks sir. This video helped me a lot
fantastic video
In the video of challenging problems of stereoisomerism , in the 7th question the structures are also diastereomers but the answer was only structural isomers
Sorry sir I got it
sir in the first problem won't thre be axial-equatorial combinations in chair form of the cyclohexane?
great video sir
sir agr hum 1st q me jo cis apne dash pe liya hai agr hum dono ko wedge me lele tb bhi to vo cis hi rehega or 2 or aajeyege GI structures
sir, in which lecture did you teach us syn/anti ? Pls provide the link
Thankuuuu Sir
Sir please tell me the number of structural and stereoisomerism for the C4 h10 o please
How is G.I possible in question 3?? Where all group are different?
Sir in question 7 if v rotate the 2nd compound and then see the configuration then it will make the pairs diastereomers
Yes,same doubt
Kuch bhi logic
Sir in last ques 1,2dimethylcyclopropane will also show gi???
But sir in example 2 POS is about CC and TT so why we don't count them as one as rotating one we will get other
Ok.... when You try to rotate them nd u will get not the exact same or identical compound because symmetry is passes through benzene's center
And
When u rotate TT u will get the TT as well
As well as CC too
They are fully different
Sir steriomerism par aur question banao sir plz for more clearance.
Sir in question no. 8 , there would be one more chain isomer i.e. 2-methylbut-1-ene ??
Is it right ?
sry sir I got it now.
in example 1 - 2min if cis not given than 8 G.I.????
sir, jee mains k lie koi video banaie
sir kya 6th question me centre of symmetry present ni hai??
Sir please problems related to entantiommer diastomer
Is it important for NEET?
no
@@atpstarkotaok sir😌,...and thanku...en videos se mere backlog ache se clear ho gye...🙏🏻
sir in q 8 DBE value should be 2 rit??
plzz help
In q.3 you did not take optical?
What is cb value?
Sir what was your rank in your first attempt?As you qualified in your drop year with a very good rank...Telling us about it would be very motivating for us.

180 how come. what was the marks distribution. was it aieee or iit screening.
in 400s.. i remember sir told in one of his videos,, jee advance mein 2000s mein
That's the speciality of a teacher, he always tries to make his students equal or better than him, and that is what sir is doing on youtube.
sir what is db value??
what is db value sir ??
Sir why u have taken pi bond in 4th question
sir What is Db value and how it calculated in ques no 3 ?.....
Double Bond Equivalent or Degree Of Unsaturation
DOU/DBE = (C+1) - {(H+X-N)/2} where C is number of Carbon, H is number of Hydrogen, X is number of Halogens and N is number of Nitrogen.
sabse last me vo 3 kya hai ?
What they are also diastereomers?
6 vaala diastereomer hai
Yes
bhai agar mujhe aiims delhi me admissin lena h to kya sir aiims entrance clear kar ne par ho jayega
sir in question no. 7 compounds should be enantiomers also
Abhishek yadav no because structure is different
Sir wo wala diasteriomer tha
5:38😂
Sir... What is DB value??
Are u an iitian??
Ab lag raha hai mujhe stereo aa gaya
Thanx sir for like
sir 1st example total should b 4×4=16
THANKS A LOT
sir but in question7 RS configuration is same so it should be identical
Sir are compounds in question 7 at 11:33 diastereomers as they are not mirror images of each other?
Krishna Deshmukh but connectivity is different .
They are not stereoisomers so we cannot talk about enantiomers and diastereomers
Sir steriomerism par aur question banao sir plz for more clearance.
