JEE Main 2024 — p Block Elements (Group 13 & 14) Question with Solution

The correct statements from the following are : (A) The decreasing order of atomic radii of group 13 elements is $\mathrm{Tl}>$ 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 ${\left[\mathrm{Al}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}$ ion is ${\mathrm{sp}}^3{\mathrm{d}}^2$. Choose the correct answer from the options given below :
