Vedclass · Answer

(D) The basic strength of amines depends on the inductive effect,solvation effect,and steric hindrance. $(a)$ For methyl-substituted amines in a polar protic solvent,the order is $Me_2NH > MeNH_2 > Me_3N > NH_3$. $(b)$ For ethyl-substituted amines in a polar protic solvent,the order is $Et_2NH > Et_3N > EtNH_2 > NH_3$. $(c)$ In the gas phase,the solvation effect is absent,and the basicity is determined by the inductive effect of alkyl groups,leading to the order $3^o > 2^o > 1^o > NH_3$ (i.e.,$Me_3N > Me_2NH > MeNH_2 > NH_3$). Since all these statements are correct,the correct option is $D$.

The correct order of basic strengths of the given amines is:
