An organic compound A gives positive test with Tollen's reagent, on treatment with amonia form B which is an eye medicine. A on treatment with concenteated KOH forms C and D. C is on oxidation forms A agains. D on acidification responds to Tollen's Test. A comines with `CH_3Mgl` followed by hydrolysis forms E, which on oxidation followed by decarboxylation forms methane. Identify A to E (only structure).

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_(5)H_(8)O_(2) is reduced to n-pentane on treatment with Zn-Hg//HCl . The compound [A] forms a dioxine with hydroxyl amine and give a positive iodoform test and Tollen's test. Identify the compound [A] and deduce its structure?
