P Block Elements

The correct statements from the following are :

(A) The decreasing order of atomic radii of group 13 elements is \(\mathrm{Tl}>\mathrm{In}>\mathrm{Ga}>\mathrm{Al}>\mathrm{B}\).

(B) Down the group 13 electronegativity decreases from top to bottom.

(C) \(\mathrm{Al}\) dissolves in dil. \(\mathrm{HCl}\) and liberates \(\mathrm{H}_2\) but conc. \(\mathrm{HNO}_3\) renders \(\mathrm{Al}\) passive by forming a protective oxide layer on the surface.

(D) All elements of group 13 exhibits highly stable +1 oxidation state.

(E) Hybridisation of \(\mathrm{Al}\) in \([\mathrm{Al}(\mathrm{H}_2 \mathrm{O})_6]^{3+}\) ion is \(\mathrm{sp}^3 \mathrm{d}^2\).
