The correct order of increasing basic nature of the following bases is
2 < 5 < 1 < 3 < 4
5 < 2 < 1 < 3 < 4
2 < 5 < 1 < 4 < 3
5 < 2 < 1 < 4 < 3
Choose the amide which on reduction with LiAlH4 yields a secondary amine
ethanamide
N-methylethanamide
N, N-dimethylethanamide
phenylmethanamide
Arrange the following amines in the decreasing order of their basic strength. Aniline (I), Benzylamine (II), p-toluidine (III)
I > II > III
II > III > I
III > II > I
II > I > III
B.
II > III > I
Among the given compounds, benzylamine (C6H5CH2NH2) is the most basic because in it lone pair of nitrogen is not involved in resonance, it is available for donation.
p-toluidine, due to the presence of electron releasing group, (-CH3 group) is more basic than aniline but less basic than benzylamine. Hence, the order of basic strength is
Which one of the following compounds will dissolve in an alkali solution after it has undergone reaction with Hinsberg reagent?
CH3NH2
(CH3)3N
(C2H5)2NH
C6H5NHC6H5
Identify the product in the following sequence
3, 4, 5-tribromobenzene
1, 2, 3-tribromobenzene

3, 4, 5-tribromonitrobenzene
Among the amines
(A) C6H5NH2
(B) CH3NH2
(C) (CH3)3N
(D) (CH3)2NH
A < B < D <C
D < C < B <A
A > B > C >D
B < C < D <A
The indicator that is obtained by coupling the diazonium salt of sulphanilic acid with N, N-dimethyl aniline is
