Question

The correct statement(s) for the following addition reactions is/are:

• A. (M and O) and (N and P) are two pairs of enantiomers
• B. Bromination proceeds through trans-addition in both the reactions
• C. M and N are identical molecules
• D. (M and O) and (N and P) are two pairs of diastereomers

Answer 1

Answer: (B), (C), (D)

(M and O) and (N and P) are two pairs of diastereomers

$B{r}_2$ in $CC{l}_4$ does anti-addition to the alkene.
Trans alkene on treatment with $B{r}_2/CC{l}_4$ gives meso products whereas cis alkene produces racemic mixture of enantiomers.


M and N are identical, hence, (M and O) and (N and P) are two set of diastereomers.
