$C_2H_5NH_2 < (C_2H_5)_2NH < (C_2H_5)_3N$

(A) In a non-polar solvent like chlorobenzene,the solvation effect (hydrogen bonding) is absent. Therefore,the basicity is determined solely by the inductive effect ($+I$ effect) of the alkyl groups. As the number of ethyl groups increases,the electron density on the nitrogen atom increases,making the amine more basic. Thus,the order of basicity is: $C_2H_5NH_2 < (C_2H_5)_2NH < (C_2H_5)_3N$.
