JEE Advanced Chemistry question

The ability of d-block elements to form complexes is due to

(A)Small and highly charged ions
(B)Vacant low energy orbitals to accept lone pair of electrons from ligands
(C)Both (a) and (b) are correctCorrect
(D)None of the above is correct

Answer: (C)

Solution

Transition metal cations are small and highly charged, giving a strong electrostatic attraction for ligand lone pairs, and they also possess vacant, energetically
