An aldehyde (A) `(C_(11)H_(8)O)`, which does not undergo self aldol condensation, gives benzaldehyde and 2 mol of (B) on ozonolysis. Compound (B) on oxidation with silver ion gives oxalic acid. Identify the compounds (A) and (B).

Explanation

To solve the problem step by step, we will identify the compounds (A) and (B) based on the given information.

### Step 1: Determine the Degree of Unsaturation
The molecular formula of compound (A) is given as \(C_{11}H_{8}O\). We can calculate the degree of unsaturation (DU) using the formula:

\[ \text{DU} = \frac{2C + 2 - H - X}{2} \]
