Note that the strongest acid is ammonia. This means that ammonia is the weakest base of the four bases. Basicity order is
ammonia < primary amine < secondary amine < tertiary amine
Introduction of a methyl group in ammonia markedly increases the basic strength of ammonia in aq. solution, introduction of the second methyl group increases only marginally the basic strength of methyl amine in water. This is due to.
A positive carbyl amine test is given by
1. N, N - Dimethyl aniline
2. 2,4 - Dimethyl aniline
3. N - Methyl - o - methyl aniline
4. p - Methyl benzyl amine
C. Tertiary butyl amine D. Isopropyl amine
The correct answer is
