MCQ

An aqueous solution containing compounds $A$ and $B$ shows optical activity. $A$ and $B$ are stereoisomers. Which of the following possibilities cannot be correct ?

✓
$A$ has two chiral centers, but $B$ does not have any because it has a symmetry plane
B
$A$ and $B$ are enantiomers
C
$A$ and $B$ are diastereomers
D
$A$ and $B$ are not present in equal amounts

✓

Answer

Correct option: A.

$A$ has two chiral centers, but $B$ does not have any because it has a symmetry plane

a
$(a)$ Compound $'B'$ may be meso but meso has plane of symmetry with chiral centres.
