Methylamine on treatment with chloroform and ethanolic caustic alkali gives foul smelling compound, the compound is

Alkyl ethylamine is heated with chloroform and alcoholic KOH, a compound with offensive smell is formed. This compound is :

An organic compound 'A' having molecular formula C_(2)H_(3)N on reduction gave another compound 'B' Upon treatment with nitrous acid, 'B' gave ethyl alcohol on warming with chloroform and alcoholic KOH, it formed an offensive smelling compound 'C'. The compound 'C' is :

When aniline is heated with chloroform and alcoholic KOH, a foul smelling product is formed. It is :

An organic compound A (C_2H_3N) is used as a solvent of choice for many organic reactions because it is not reactive in mild acidic and basic conditions. Compound A on treatment with Ni/ H_2 fo rms B. When B is treated with nitrous acid at 273K, ethanol is obtained. When B is warmed with chloroform and NaOH, a foul smelling compound C is formed. Identify A to C along with their structures and given reactions.
