An organic compound A, `C_(8)H_(6)` on reacting with dil. `H_(2)SO_(4)` and `HgSO_(4)` gives a compound 'B'-which can also be obtained from reaction of benzene with acid chloride in the presents of anh. `AlCl_(3)` Compound B when reacted with iodine and aq. NaOH yields C and a yellow compound D. Identify A to D with proper justification.

Text Solution

Verified by Experts

(i) As the compound [B] can be formed by reacting benzene with acid chloride in the presence of anydrous `AlCl_(3)`, It is an aromatic ketone.
(ii) Since the compound [B] gives iodofrom [D] as one of the product on reacting iodine and aquoeus `NaOH`, the compound [B] is acetophenone.
(iii) The compound [A] seems to be a derivative of acetylene since it undergoes hydration under acidic conditions to form [B] which is a ketone i.e., acetophenone.
The sequence may be shown as follows:
