An organic compound A `(C_3H_5N)` when heated with concentrated `NaOH, NH_3` gas evolved with formation of a sodium salt of carborylic acid (B). On reduction A give `C(C_3H_9N)C` when treated with Nitrous acid gives D. Find A,B,C,D and writes the relevant reactiosn involved.

An organic compound 'A' (C_2H_6O) reacts with sodium to form a compound 'B' with the evolution of hydrogen gas and gives a yellow compound 'C' when treated with iodine and NaOH. When heated with conc. H_2SO_4 at 140^@C it gives a compound 'D' C_4H_(10) which on treatment with HI at 100^@C gives 'E'. 'B' when heated with 'E' also gives back 'D'. Identify 'A' to 'E' and write equations for the reaction involved.

Two isomeric compound A & B have general formula C_4H_8O_2 ,A on hydrolysis gives methanlo and a carboxylic acid (C)_1 D on reduction forms ethanol identify A, B, C,& D.

An organic compound A (C_8H_6) reacts with dilute H_2SO_4 in presence of mercuric chloride to produce another compound (B) . B is also obtained when benzene reacts with an acid chloride in presence of anhyd. AlCl_3 . Identify A and B and give the reactions involved.

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.

An organic compound (A) with molecular formula C_(6)H_(7)N gives (B) with HNO_(2)//HCl at 273 K. The aqueous solution of (B) on heating gives compound (C) which gives violet colour with neutral FeCl3. Identify the compounds A, B and C and write the equations.

A compound (A) (C_7H_4N) on hydrolysis with strong aqueous acid gives another compound (B) on treatment with ammonia gives a salt which on heating gives (C). The compound (C) undergoes Hofmann's bromamide reaction to yield aniline. Identify A, B, C and write chemcial reactions involved.

An ether A (C_5H_(12)O) when heated with excess hot concentrated HI produced two alkyl halides which on hydrolysis give B and C. Oxidation of B gives an acid D whereas oxidation of C gives ketone E. Both B and C give haloform reaction. Identify A to E along with their structures and the given reactions.
