A sweet smelling organic compound (A) is slowly oxidised by air in presence of light to a highly poisonous gas on warming with silver powder, it forms a gaseous substance (B), which is also produced by the action of calcium carbide on water. Identify (A) and (B) and write the chemical equations of the reactions involved.

A sweet smelling organic compound 'A' is slowly oxidised by air in presence of light to a higly posionous gas. On warming compound A with silver powder, it forms a gaseous substance 'B' which is also produced by the action of calcium carbide on water. identify 'A' and 'B' and write the chemical reactions involved.

A blackish brown coloured solid 'A' when fused with alkali metal hydroxides in presence of air, produces a dark green coloured compound 'B' which on electrolytic oxidation in alkaline medium gives a dark purple coloured compound 'C' Identify A, B and C and write the reactions involved.

A Ketone 'A' Which undergoes haloform reac-tion gives compound B on reduction. B oheatign with H_2SO_4 gives compound C, which forms mono-ozonide D. D on hydroly-sis in presence of Zn dust gives only acetaldehyde. Identify A, B and C. Write down the reactions involved.

An organic compound contains A(C_7H_5N) on hydrolysis with strong aqueous acid gives another compound B which is a monobasic aromatic carboxylic acid. The 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. Name A, B and C and write the chemical reactions involved.

Two moles of organic compound 'A' on teratment with a strong base give two compounds 'B' and 'C'. Compound 'B' on dehydrogenation with Cu gives 'A' while acidification of 'C' yield carboxylic acid 'D' with molecular formula of CH_2O_2 . Identify the compounds A, B, C and D. Write all chemical reactions involved.

An organic compound has the molecular formula C_5H_(10)O . The compound does not reduce Tollen's reagent but reacts with Brady's re-agent to give orange precipitate. On vigorous Oxidation, the molecule produces ethanoic acid and propanoic acid. The com-pound also gives iodoform test. Identify the compound and write equations for chemical reactions involved.

An organic compound (A) (molecular formula, C_4H_8O_2 ) was hydrolysed with dilute H_2SO_4 to give a carboxylic acid (B) and alcohol (C ). Oxidation of (C ) with chromic acid produced (B). Write possible structures of (A), (B) and (C ) and give their IUPAC name. Write the chemical equations involved in the process.
