Identify A and B.

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 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.

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.

Identify A, B, C and D in the following conver-sions: A overset(NaNO_2//HCI)underset(273-278)(rarr)CH3OH overset(PCl)(rarr)B overset(KCN)(rarr) underset(D)underset(darrLiAIH_4)(C)

(i) A substance A (a mild non-corrosive base) used in cooking when heated gives another powder B. (ii) When powder A is mixed with a mild edible acid, it libreates a gas C. (iii) When powder B is recrystallised, it gives another powder D having detergent properties. Identify A, B C and D. Write the equation for the conversion taken place.
