What is the correct name for the following complex? `[Co(NH_2)_2(NH_2 -CH_3)_2]Cl`

Options

A. Diamidodimethylaminecobalt(III) chloride.
B. bis(Methylamine) diamidocobalt (II) chloride
C. Diamidobis (methylamine) cobalt (II) chloride
D. Diaminedimethylaminecobalt(III) chloride

Answer

C

Explanation

`(NH_2^(-))` is named as amido, so `(NH_2^(-))_2` iş named diamido, `MeNH_2`, is named methylamine. For `(MeNH_2)_2`- ligand, bis convention is followed to avoid confusiorrwith ligand `Me_2NH` - whose name is dimethylamine. Thus, the correct name of the complex is diamidobis (methylamine) cobalt(III) chloride .
