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).

Explanation

To solve the problem step by step, we will identify the compounds (A) to (F) based on the information provided in the question.

### Step 1: Identify Compound A
Given that compound (A) has the formula \(C_5H_7OCl\) and reacts with ethanol to form compound (B) \(C_7H_{12}O_2\), we can deduce that compound (A) is likely an allylic chloride. The presence of the carbonyl chloride (COCl) suggests that it is a chloroalkene.

**Assumption**: Compound (A) is likely 3-chlorobut-2-ene:
