Question

An ambidentate ligand is one which –

• A. is linked to the metal atom at two points
• B. has two donor atoms but only one of them has the capacity to form a coordinate bond
• C. has two donor atoms but either of the two can form a co-ordinate bond
• D. forms chelate rings

Answer 1

Answer: (C)

Ambident ligands contain more than one donor sites (donor atoms), but only one can donate lone pair at a time. Given ligands have two donor atoms ex: $\overset{\Theta}{C}N,\overset{\Theta}{N}O_{2}$
