The correct statement on the isomerism associated with the following complex ions. (a) N i H 2 O 5 N H 3 2 + (b) N i H 2 O 4 N H 3 2 2 + and (c) N i H 2 O 3 N H 3 3 2 + is:

Options

  1. A(a) and (b) show only geometrical isomerism
  2. B(a) and (b) show geometrical and optical isomerism
  3. C(b) and (c) show geometrical and optical isomerism
  4. D(b) and (c) show only geometrical isomerism

Correct answer

D. (b) and (c) show only geometrical isomerism

Step-by-step solution

N i H 2 O 5 N H 3 2 + does not show any isomerism N i H 2 O 4 N H 3 2 2 +   shows cis-trans (geometrical) isomerism N i H 2 O 3 N H 3 3 2 + shows fac-mer isomerism
