💡 Solution & Explanation

Zeise’s salt   3 2 4 K PtCl C H has Square planar geometry.    3 2 Co en NH 2Cl      is inner orbital octahedral 2 3 d sp complex and has 3 G.I and 2 optical isomers.   4 FeCl has higher spin-only magnetic moment as it has 5 unpaired electron than    3 2 Co en NH 2Cl      which has only 1 unpaired electron. In option (D) The cobalt ion in    2 2 2 Co en NH3      has 2 3 d sp hybridization as both act as SFL for Co+2.
