Work Step by Step

Bronsted acids are compounds capable of donating a proton. Therefore, they need a (H), and that hydrogen needs to be capable of leaving the molecule. - The $OH^-$ and the $NH_2^-$ have hydrogens, but, they cannot donate them. Brosted bases are compounds capable of receiving a proton. Therefore, they need a lone pair for receiving this proton. - The $H_3O^+$, $HBr$ and $HCN$ have lone pairs, but they don't, normally, receive a proton.
