A neutral compound (A) C_3H_6O_2 is formed by the reaction of an acid (B) which is present in ant's sting and an alcohol (C) which is used in the preparation of tincture of iodine. Identify the compounds B and C?

(a) (i) Explain the reduction of nitrocompound of nitrocompounds to amines with an example . (ii) Why aromatic primary amines cannot be prepared by Gabriel synthesis ? (b) How is aniline converted into phenyl isocyanide? Write the equation .

The silicons ae organosilicon polymers containing Si-O-Si linkage. They are usually prepared by hydrolysis of alkylchlorosilanes, the silanols formed as intermediates on hydrolysis condense by intermolecular elimination of water with the formation of Si-O-Si linkage underset(-O-Si(CH_(3))_(2)-O-Si(CH_(3))-O-Si(CH_(3))_(2)-O-)underset(|)underset(O)underset(|)(-O-Si(CH_(3))_(2)-O-Si(CH_(3))-O-Si(CH_(3))_(2)-O-) The above silicone can be obtained by hydrolysis of which of the following ?

Hydrolysis is an acid-basedreaction of a cation or anion or both ions of a salt with water, Resultan solution of hydrolysis may be acidic, basic or netural. The anion A^(-) which is a weakeer base than OH^(-) and which his its conjugate acid HA stronger then water but weaker than H_(3)O shown the phenomenon of hydrolysis Ex : CH_(3)COO^(-),CN^(-),NO_(2)^(-) etc. The contion B^(+) which is a weaker acid than H_(3)^(+) which is a weaker acid then H_(3)^(+) and which has its conjugate base BOH stronger than water but weak than OH^(-) shown the phenmenon of hydrolysis Ex : NH_(4)^(+)C_(6)H_(5)NH^(+),N_(2)H_(5)^(+) etc. The hydrolysis constant of anion and cation are given by A^(-)(aq.)+H_(2)O(l)hArrHA(aq.)+OH^(-)(aq) " " K_(h)=(K_(w))/(K_(a))rArr([HA(aq.)][OH^(-)(aq.)])/([A^(-)(aq.)]) B^(+)(aq.)+H_(2)O(l)hArrBOH(aq.)+H^(+)(aq.)
