Give the chemical test of distinguish between : `CH_(3)CHO and C_(6)h_(5)CHO`.

Explanation

To distinguish between acetaldehyde (CH₃CHO) and benzaldehyde (C₆H₅CHO), we can use the Fehling's test. Here’s a step-by-step solution:

### Step 1: Prepare Fehling's Solution
Fehling's solution is prepared by mixing two solutions:
- **Fehling's A**: A solution of copper(II) sulfate (CuSO₄).
- **Fehling's B**: A solution of sodium hydroxide (NaOH).

### Step 2: Add the Aldehyde
