The complex that can show optical activity is :

Options

  1. Atrans - Cr Cl 2 ( Ox ) 2 3 -
  2. Btrans − Fe NH 3 2 CN 4 −
  3. Ccis - Fe NH 3 2 ( CN ) 4 -
  4. Dcis − CrCl 2 ox 2 3 − ox = oxalate

Correct answer

D. cis − CrCl 2 ox 2 3 − ox = oxalate

Step-by-step solution

Only cis - CrCl 2 OX 2 3 - show optical isomerism while its trans form do not show optical isomerism due to presence of plane of symmetry.
