An organic compound (A) having C = 16.27%,H = 0.677%, Cl = 72.203% reduces Fehling solution and on oxidation gives an acid (B) having C = 14.679%, H = 0.612% and Cl = 65.137%. (B) on distillation with sodalime gives a sweet smelling liquid (C) which contains 89.12% chlorine. (C) can also be obtained by heating (A) with alkali. (A) can also be obtained by the action of Cl2 on `C_2 H_5 OH`. Identify (A), (B) and (C) and explain the reactions.

Explanation

Molecular formula of `(B) = C_(2)HCl_(3)O_(2)`
Comnpound `(A0` shows positive Tollens test so it contains `(-CHO)` group.
Sturcture of `(A)=(overset(C_2HOCl_3)(-CHO))/(underline(Cl_3C-CHO))`
`(A)` is chlorol.

Percentage of `Cl` in `CHCl_(3)` (molecular mass of `CHCl_(3) = 12 + 2 + 35.5xx3 = 119.5`)
`= (106.5)/(119.5) xx 100 = 89.12%`
