An amide 'A' with molecular formula C₇H₇ON undergoes Hoffmann Bromamide degradation reaction to give amine 'B'. B on treatment with nitrous acid at 273-278 K form 'C' and on treatment with chloroform and ethanolic potassium hydroxide forms 'D'. 'C' on treatment with ethanol gives 'E'. Identify 'A', 'B', 'C' 'D' and 'E.' and write the sequence of chemical equations.
Arrange the following compounds in the increasing order of their basic strength in gaseous phase : C₂H₅NH₂, (C₂H₅)₃ N, (C₂H₅)₂ NH
Give reasons for the following :
The action of nitrous acid on ethylamine gives mainly :
