An organic compound `A(C_(6)H_(6)O)` gives dark green colouration with ferric chloride. On treatment with `CHCl_(3) and KOH`, followed by acidification gives compound B. Compound B can also be obtained from compound C on reaction with pyridinium chlorochromate (PCC). Identify A, B and C

An organic compound ‘A’ C_(8)H_(6) on treatment with dilute H_(2)SO_(4) containing mercuric sulphate gives compound ‘B’. This compound ‘B’ can also be obtained from a reaction of benzene with acetyl chloride in presence of anhy AlCl_(3) . ‘B’ on treatment with I_(2) in aq. KOH gives ‘C’ and a yellow compound ‘D’. Identify A, B, C and D. Give the chemical reactions involved.

An organic compound (A) (C_(6)H_(10)O) on reaction with CH_(3)MgBr followed by acid treatment gives compound (B). The compound (B) on ozonolysis gives compound (C ), which in the presence of a base gives 1-acetyl cyclopentane (D). The compound (B) on reaction with HBr gives compound (E ). Write the structures of (A), (B), (C ), (D), and (E ). Show how (D) is formed from (C ).

A compound C_6H_6O gives violet color with FeCl_3 and reacts with CHCl_3//KOH to give B

An organic compound 'A' having molecular formula C_(6)H_(6)O gives a characeristic colour with aqueous FeCl_(3) solution. When 'A' is treated with CO_(2) and NaOH at 400 K under pressure, compound 'B' is obtained. The compound 'B' upon acidification gives compound 'C' which reacts with acetyl chloride to form 'D'. It is a polular pain killer. Deduce the structures of A, B, C and D.
