Vedclass · Answer

(D) In the $p$-block elements of group $13$,the acidic character of hydroxides depends on the ionization energy and the size of the central atom.$B(OH)_3$ (also written as $H_3BO_3$) is orthoboric acid,which acts as a weak Lewis acid by accepting an $OH^-$ ion from water.$Al(OH)_3$ and $Ga(OH)_3$ are amphoteric in nature.$Tl(OH)_3$ is basic in nature due to the large size and low ionization energy of $Tl$.
