Vedclass · Answer

(D) Bronsted acid must be a proton $(H^+)$ donor. $CCl_4$ does not contain any hydrogen atoms,so it cannot act as a Bronsted acid.$A$ Lewis acid is an electron-pair acceptor. In $CCl_4$,the carbon atom has a complete octet and cannot accept an electron pair. Therefore,$CCl_4$ cannot act as a Lewis acid.$BF_3$,$AlCl_3$,and $SnCl_4$ have incomplete octets or vacant d-orbitals,allowing them to act as Lewis acids.Thus,the correct option is $(D)$.
