# Which of the following statement is correct?(Here $R=CH_3$)

$\begin{array}{1 1}(a)\;\text{In aqueous solution, }R_2NH(2^oamine)\text{ is a stronger base than } RNH_2(1^oamine)\\(b)\;\text{In aqueous solution, }R_3N(3^oamine)\text{ is a stronger base than } R_2NH(2^oamine)\\(c)\;\text{In aqueous solution }R_3N \text{ is a stronger base than }RNH_2\\(d)\;\text{Above all}\end{array}$

Can you answer this question?

The base strength of aliphatic amines decided by the following two factors
(i) Inductive factor
(ii) Solvation factor
Induction and solvation operate in opposite directions.So in aqueous solution $R_2NH > RNH_2$
Hence (a) is the correct answer.
