An organic compound (A) with molecular formula `C_8H_8 O` forms an orange red precipitate with 2,4 -DNP reagent and gives yellow precipitate on heating with iodine in the presence of sodium hydroxide . It neither reduces Tollen's reagent or Fehling's solution , nor does it decolourise bromine water or Baeyer's reagent. On drastic oxidation with chromic acid, it gives a carboxylic acid (B) having molecular formulae `C_7H_6O_2`. Identify the compound (A) and (B) and explain the reactions involved .

Explanation

To solve the problem, we need to identify the organic compound (A) with the molecular formula C8H8O and the carboxylic acid (B) it produces upon oxidation. We will analyze the information provided step by step.

### Step 1: Analyze the Molecular Formula
The molecular formula of compound (A) is C8H8O. This indicates that it is likely an aromatic compound due to the degree of unsaturation (which suggests the presence of a ring structure).

**Hint:** Look for the presence of an aromatic ring based on the degree of unsaturation.
