C_(7)H_(10)O reacts with CH_(3)MgBr r to give a compound C_(8)H_(10)O which gives the test with iodoform, than fine out structure of A

An organic compound (A) (C_(5)H_(7)OCl) reacts rapidly with ethanol to give (B) (C_(7)H_(12)O_(2)) . (A) also reacts with water to produce an acid which reacts with bromine to give (C ) (C_(5)H_(8)Br_(2)O_(2)) . (B) on boiling with H_(2)SO_(4) forms an acid (D). When (D) is oxidised with KMnO_(4) an acid (E ) (C_(4)H_(6)O_(3)) is produced. On mild heating, (E ) gives (F) (C_(3)H_(6)O) which cannot be oxidised by ammoniacal AgNO_(3) . Identify the compounds (A) to (F).
