Vedclass · Answer

(A) Lewis base is a substance that can donate a lone pair of electrons. The strength of a Lewis base is inversely proportional to the electronegativity of the atom carrying the lone pair. Comparing the atoms $C$,$N$,$O$,and $F$ in the same period of the periodic table,electronegativity increases in the order $C Therefore,the basicity (ability to donate electrons) decreases in the order $CH_3^- > NH_2^- > OH^- > F^-$. $CH_3^-$ is the strongest Lewis base because carbon is the least electronegative among the given atoms,making its lone pair most available for donation.

Which of the following is the strongest Lewis base?
