Question

The following complexes are given :<br>(1) trans-[Co(NH3)4Cl2]+ (2) cis-[Co(NH3)2(en)2]3+<br>(3) trans-[Co(NH3)2(en)2]3+ (4) NiCl4^2-<br>(5) TiF6^2- (6) CoF6^3-<br>Choose the correct code :

Answer: B

💡 Solution & Explanation

cis-[Co(NH3)2(en)2]3+ lacks a plane of symmetry (optically active). The trans forms have a plane of symmetry (optically inactive).
