JEE Main Chemistry question

High basicity of relative to is attributed to [Jamia Millia Islamia 2006]

(A)the effect of solventCorrect
(B)the inductive effect of Me
(C)the shape of
(D)the shape of

Answer: (A)

Solution

On a purely inductive basis, (three electron-donating methyl groups) should be the strongest base, yet in aqueous/protic solvents is found to be more basic. This reversal is explained by differential solvation: the ammonium ion formed from (having two N–H bonds) is
