QJEEM20Ch4cee: JEE Main 2020 Chemistry - Class 12 JEEM20Ch4cee Solution: Consider the complex ions, trans-[Co(en) 2 Cl 2 ] + (A) and…

Consider the complex ions,
trans-[Co(en)2Cl2]+ (A) and
cis-[Co(en)2Cl2]+ (B).
The correct statement regarding them is :

Multiple Choice Options

  • A both (A) and (B) can be optically active.
  • B both (A) and (B) can not be optically active.
  • C (A) can not be optically active, but (B) can be optically active.
  • D (A) can be optically active, but (B) can not be optically active.

Step-by-Step Verified Solution

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.
