IUPAC name of `[Co(NH_3)_5NO_2]Cl_2`

A

(a) Pentamminenitrocobalt (III) chloride

B

(b) Pentaminenitrosocobalt (III) chloride

C

(c) Pentaminenitrocobalt (II) chloride

D

(d) None of these

Text Solution

Verified by Experts

The correct Answer is:
A
In the compounds `[Co(NH_3)_5NO_2]Cl_2`, the oxidation state of cobalt is `+3` and here `5NH_3` ligands, a `NO_2` ligand are attached to the central atom. Therefore its name is pentaamminenitrocobalt (III) chloride.
