Give one chemical test to distinguish between the following pairs of compounds :
Phenol and benzoic acid.

Explanation

To distinguish between phenol and benzoic acid, we can perform the neutral FeCl3 test. Here’s a step-by-step solution:

### Step 1: Prepare the Samples
Take two separate test tubes. In one test tube, add a small amount of phenol, and in the other test tube, add a small amount of benzoic acid.

### Step 2: Add Neutral FeCl3 Solution
To both test tubes, add a few drops of neutral iron(III) chloride (FeCl3) solution.
