For the following which option represent correct order
(A) Atomic size : Tℓ > In > Ga > Aℓ > B
(B) Ionization Enthalpy : B > Tℓ > Ga > Aℓ > In
(C) Lewis acidic character : BF3 > BCl3 > BBr3 > BI3
(D) Acidic nature : B2O3 > Al2O3 > Ga2O3 > In2O3
Options:
Answer:
D
Solution:
The correct orders are:
(B) Ionization Enthalpy: B > Tl > Ga > Al > In (due to poor shielding by d and f electrons in Ga, Tl).
(D) Acidic nature of oxides: B₂O₃ > Al₂O₃ > Ga₂O₃ > In₂O₃ (acidic character decreases down the group).
