Which of the given statement(s) about N, O, P and Q with respect to M is / are correct?
M and P are enantiomers
Converting all of them into Fischer projection.
Since, M and N have – OH on same side and opposite side respectively, they cannot be mirror image, they are diastereomers.
M and O are identical.
Note Fischer projection represents eclipse form of Sawhorse projection.
For comparison purpose, similar types of eclipse conformers must be drawn i.e. both vertically up and down.
M and P are non – superimposable mirror images, hence, enantiomers.
