Phenol has smaller dipole moment than methanol. Why?

Explanation

To understand why phenol has a smaller dipole moment than methanol, we need to analyze the structures and the electronic effects in both compounds. Here’s a step-by-step breakdown:

### Step 1: Define the Compounds
- **Phenol (C6H5OH)**: It consists of a benzene ring (C6H5) attached to a hydroxyl group (OH).
- **Methanol (CH3OH)**: It consists of a methyl group (CH3) attached to a hydroxyl group (OH).

### Step 2: Understand Dipole Moment
- The dipole moment is a measure of the polarity of a molecule. It is influenced by the difference in electronegativity between the atoms and the distance between them.
