Complex compound [Cr(NCS)(NH3)5][ZnCl4] will be : — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Step 1: Check the magnetic properties of the complex: the cation contains Cr^3+ (3d^3), which has three unpaired electrons and is paramagnetic, ruling out (a), (b), and (d). Step 2: Transition metal complexes of Cr^3+ are colored (typically green). Step 3: Because the compound contains both a complex cation and complex anion, it can show coordination isomerism (by exchanging ligands between the metal centers). Thus, option (c) is correct.
