The correct statement(s) for the following addition reactions is(are)
Options
- AO and P are identical molecules
- B(M and O) and (N and P) are two pairs of enantiomers
- C(M and O) and (N and P) are two pairs of diastereomers
- DBromination proceeds through trans-addition in both the reactions
Correct answer
C. (M and O) and (N and P) are two pairs of diastereomers
Step-by-step solution
(M) and (N) are identical meso compounds (O) and (P) are enantiomers Explanation of 4 options : (i) (M) and (O) are distereomers of each other. (N) and (P) are distereomers of each other. (ii) Addition of B r 2 on alkene follows non-classical carbocation mechanism. It is anti or trans addition. (iii) (O) and (P) are enantiomers (iv) (M) and (N) are identical and (O) and (P) are enantiomers. (M and O) are distereomers and (N and P) are distereomers.
