Question

Which of the ligands can show linkage isomerism?

• A. $CNS$
• B. $N{O}_2$
• C. $CN$
• D. All of these

Answer 1

The correct option is D All of these

Linkage isomers are two or more coordination compounds in which the donor atom of at least one of the ligands is different (i.e., the connectivity between atoms is different). All of these ligands can show linkage isomerism. $CN{S}^{-}$ can attach through either $N$ side or $S$ side. $N{O}_2^{-}$ can attach either through $N$ side or $O$ side. $C{N}^{-}$ can attach through either $C$ side or $N$ side.
