Vedclass · Answer

(C) The complex $[Cr(NCS)(NH_3)_5][ZnCl_4]$ consists of a cationic part $[Cr(NCS)(NH_3)_5]^{2+}$ and an anionic part $[ZnCl_4]^{2-}$.In the cationic part,$Cr$ is in the $+3$ oxidation state ($d^3$ configuration),which has three unpaired electrons in the $t_{2g}$ orbitals,making it paramagnetic and responsible for the green colour.Since both the cationic and anionic parts are complex ions,this compound exhibits coordination isomerism.

The complex compound $[Cr(NCS)(NH_3)_5][ZnCl_4]$ will be:
