Answer» Correct Answer - B `1^@` amine forms `N-`alkyl benzene sulphonamide with `C_6H_5SO_2Cl`, which if soluble is alkali. `2^@` amine forms N, N-dialkyl benzene sulphonamide, which is insoluble in alkali as well as acid. `3^@` amines do not react with `C_6H_5SO_2Cl` and hence are soluble in acid. Thus, A,B and C here represent `1^@,2^@` and `3^@`. |
