Question

why do Transition metals form large number of complex compounds

Answer 1

According to this model, transition-metal ions form coordination complexes because they have empty valence-shell orbitals that can accept pairs of electrons from a Lewis base. Ligands must therefore be Lewis bases: They must contain at least one pair of nonbonding electrons that canbe donated to a metal ion.

Answer 2

Hey !!

Transition metal form a large number of complex compound because it is due to small size and high ionic change / availability of d orbitals.

DETAILED EXPLANATIONS

This is due to the comparatively smaller sizes of the metal ion, their high ionic charges and the availability of d - orbitals for bond formation.

Good luck !!
