JEE · NEET Previous Year Question

$Which one of the following complexes is not expected to exhibit isomerism?$

Topic: NEET PYQ

Answer: C. Full step-by-step solution below.

A $[N i (N H_{3})_{4} (H_{2} O)_{2}]^{2 +}$
B $[P t (N H_{3})_{2} C l_{2}]$
C $[N i (N H_{3})_{2} C l_{2}]$
D $[N i (e n)_{3}]^{2 +}$

Correct answer: C

Solution

(c) Compounds having tetrahedral geometry does not exhibit isomerism due to presence of symmetry elements. Here, (Ni (NH_{3})_{2} Cl_{2}) has tetratedral geometry .
