Newman to Sawhorse to Fischer (Interconversion)

Last problem in this lecture no isomeric pair has given, C& D are diastereomers, CSIR answer key for this question was wrong.
In this video, I have explained the Interconversion of Newman projection formula, Sawhorse and Fischer projection formula with the help of number of examples. The concept is very important to understand stereochemical aspects. It is must topic for IIT JAM, CSIR NET and GATE entrance examinations.

Last problem(CSIR NET DEC.2015) in this lecture no isomeric pair has given, C& D are diastereomers, CSIR answer key for this question was wrong.

[@prachimall2312]

very nice sir.

[@simranaggarwal2431]

Isn't the last answer wrong?
Because if configuration of one of the carbon remain intact n for the other one changes then they are diastereomers and noy enantiomers.

[@TETRAHEDRONCHEMISTRYCLASSES]

Yes Simran you are write they are diastereomers, I followed csir answer key which was wrong for this question. Thank you.

[@ramanswami7263]

Nice lecture sir... Only last problem is wrong...

[@TETRAHEDRONCHEMISTRYCLASSES]

Yes... I Have pinned a comment regarding this question.

[@Samanvi356]

If lowest priority group is other than hydrogen like methyl...
Can we change configuration sir

[@TETRAHEDRONCHEMISTRYCLASSES]

Yes, on changing the projection of any lowest priority group (be it H, Me or any other) configuration will also change.

Sir I'm having an example of the chiral carbon in Fischer projection. But lowest priority group will be on horizontal bond if it's not be hydrogen then can we change configuration after viewing the molecule s to r
R to s.... Plz give clarity..

[@TETRAHEDRONCHEMISTRYCLASSES]

Indeed you can do.

Thanks you sir ❣️❣️
