Vedclass · Answer

(D) Bronsted acid is a proton $(H^+)$ donor. $HSO_4^-$,$HNO_3$,and $NH_3$ (in specific conditions) can act as Bronsted acids because they contain hydrogen atoms that can be donated.$BCl_3$ is an electron-deficient compound with only $6$ electrons in the valence shell of the Boron atom. Therefore,it acts as a Lewis acid (electron pair acceptor) but cannot act as a Bronsted acid because it lacks a hydrogen atom to donate.
