Which of the statements are correct?
where (B) and (C) are:
Enantiomers if R≠R′. .
Diastereomers if R≠R′.
Both are meso and hence the same compound if R = R'.
An equimolar mixture of (B) and (C) is a racemic mixture if R≠R′.
If R and R' are different (i.e., R≠R′ (If R=Me,R′=Et :
If R and R' are same (i.e., R = R')
