JEE MAIN - Chemistry (2020 - 5th September Evening Slot - No. 8)

Consider the complex ions,
trans-[Co(en)2Cl2]+ (A) and
cis-[Co(en)2Cl2]+ (B).
The correct statement regarding them is :
both (A) and (B) can be optically active.
both (A) and (B) can not be optically active.
(A) can not be optically active, but (B) can be optically active.
(A) can be optically active, but (B) can not be optically active.

Explanation

trans-[Co(en)2Cl2]+ contain a plane of symmetry. It cannot be optically active.

cis-[Co(en)2Cl2]+ does not contain any plane of symmetry. Hence the compound (B) is optically active.
