Vedclass · Answer

(A) $Lewis$ acid is defined as an electron pair acceptor. Transition metal ions have vacant $d$-orbitals which can accept electron pairs from ligands to form coordinate bonds. This ability to accept electron pairs allows them to act as $Lewis$ acids,which is a fundamental requirement for the formation of coordination complexes.
