Vedclass · Answer

(C) Lewis base is defined as a substance that can donate a lone pair of electrons.$H_2O$ has two lone pairs on the oxygen atom,$NH_3$ has one lone pair on the nitrogen atom,and $F^{-}$ has four lone pairs on the fluorine atom.$CH_4$ (methane) has a stable octet configuration with all valence electrons involved in bonding,and it has no lone pairs to donate.Therefore,$CH_4$ cannot act as a Lewis base.
