Write the structures of main products when aniline reacts with the following reagents:
(i) Br2 water
(ii) HCl
(iii) (CH3CO)2O/pyridine
Arrange the following in the increasing order of their boiling point: C2H5NH2, C2H5OH, (CH3)3N
Give a simple chemical test to distinguish between the following pair of compounds:
(CH3)2NH and (CH3)3N.
Arrange the following compounds in increasing order of solubility in water:
C6H5NH2, (C2H5)2NH, C2H5NH2
The increasing order of solubility in water of the given compounds is as follows:
C6H5NH2 < (C2H5)2NH < C2H5NH2
The more extensive the hydrogen bonding, the higher is the solubility of the compound in water. C2H5NH2 contains two H-atoms, whereas (C2H5)2NH contains only one H-atom. Therefore, C2H5NH2 is more soluble than (C2H5)2NH. The solubility of C6H5NH2 is least due to its high molecular mass.
Arrange the following compounds in an increasing order of their solubility in water:
C6H5NH2, (C2H5)2NH, C2H5NH2
