Vedclass · Answer

(B) Lewis acid is defined as an electron pair acceptor.$AlCl_3$ is an electron-deficient compound because the central $Al$ atom has only $6$ electrons in its valence shell.Therefore,it can accept a lone pair of electrons to complete its octet,making it a Lewis acid.$NaCl$ is an ionic salt,while $NH_2^-$ and $F^-$ are Lewis bases because they have lone pairs of electrons to donate.
