$NH_3$

Vedclass · Answer

(A) $1$. $A$ $Lewis$ base is a substance that can donate a lone pair of electrons. $NH_3$ has a lone pair on the nitrogen atom,making it a strong $Lewis$ base.$2$. $A$ $Bronsted$ acid is a proton $(H^+)$ donor. $NH_3$ can lose a proton to form $NH_2^-$,thus acting as a $Bronsted$ acid.$3$. $A$ $Bronsted$ base is a proton $(H^+)$ acceptor. $NH_3$ can accept a proton to form $NH_4^+$,thus acting as a $Bronsted$ base.$4$. Therefore,$NH_3$ satisfies all three criteria.
