Vedclass · Answer

(D) Lewis acid is defined as an electron-pair acceptor. $AlCl_3$ and $BeCl_2$ are electron-deficient compounds (incomplete octet),so they act as Lewis acids. $HSO_4^-$ can accept a proton or an electron pair in certain conditions. $NH_3$ has a lone pair of electrons on the nitrogen atom,which it can donate. Therefore,$NH_3$ acts as a Lewis base,not a Lewis acid.
