Among 1-4, the complexes that can show geometrical isomerism are 1 . [ Pt ( N H 3 ) 3 Cl ] + 2 . [ Pt ( N H 3 ) C l 5 ] – 3 . [ Pt ( N H 3 ) 2 Cl ( ONO ) ] 4 . [ Pt ( N H 3 ) 4 ClBr ] 2 +

Options

  1. A4 and 1
  2. B2 and 3
  3. C3 and 4
  4. D1 and 2

Correct answer

C. 3 and 4

Step-by-step solution

Pt NH 3 2 Cl ONO and Pt NH 3 4 ClBr 2+ MA 2 BC ⇒ 2 .G .I MA 4 BC ⇒ 2 .G .I Hence these two can show geometrical isomerism.
