Group `13` elements form complexes much more readily than the `s`-block elements because ofA. smaller ionic sizeB. increased ionic chargeC. higher charge densityD. all of these

Answer» Correct Answer - C
Both tetrahedral complexes such as `Li[AlH_(4)]` and `Na[BH_(4)]`, and octahedral complexes such as `[GaCl_(6)]^(3-)`, `[InCl_(6)]^(3-)`, and `[TlCl_(6)]^(3-)` are known.
