Cyclohexanamine is heated with chloroform and caustic potash to give 'X'. 'X' is subjected to reduction to give 'Z'. Functional isomer of 'Z' is

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

Formaldehyde when treated with KOH (caustic potash) gives methanol and potassium formate, the reaction is known as

An organic compound P on reduction gives compound Q which on reaction with chloroform and potassium hydroxide forms R. The compound R on catalytic reduction gives N-methylaniline. The compound P is

Benzoic acid is treated with SOCl_2 and the product (X) formed is reacted with ammonia to give (Y). (Y) on reaction with Br_2 and KOH gives (Z). (Z) in the reaction is

Compound 'X' containing chlorine, on treatment with NH_(3) gives a solid 'Y' which is free from chlorine. (Y) analysed as C=49.31%,H=9.59% and N=19.18% and reacts with Br_(2) and caustic soda to give a basic compound (Z),(Z) reacts with HNO_(2) to give ethanol. Suggest structure of (X), (Y) and (Z).

A Hydrocarbon X (M.F. C_4H_6 ) produces an aldehyde Y through Hydroboration Oxidation and a ketone Z through Oxymercuration Demercuration. Y and Z are functional isomers. X gives P when treated with excess of HOCl and Q when treated with excess of HCl. The correct statement is :

Primary alkyl halide C_4H_9Br (X) reacts with alc. KOH to give compound (Y). (Y) reacts with HBr to give compound (Z) which is an isomer of (X). When (X) reacts with Na metal it gives compound (P). (X), (Y), (Z) and (P) are

Show that the function f: Z->Z defined by f(x)=x^2 for all x in Z , is a function but not bijective function.
