Question

Q. The process of conversion of an optically pure enantiomer into an optically inactive equimolecular mixture of

(+)

and

(-)

enantiomers is called:

Answer 1

Rule : cis compound + anti-addition of

Br2→ Product is racemic
trans compound + anti-addition of

Br2→ Product is meso (when

R= R′)

Answer 2

So, (C) is an equimolar mixture of two enantiomeric compound and (F) is a single compound and is optically inactive. Hence, options A & B are correct.
