Question:
Explain the reason of solubility of alcohol and phenol in water.
Explain the reason of solubility of alcohol and phenol in water.
Show Hint
Hydrogen bonding increases solubility in polar solvents like water. Short-chain alcohols are more soluble than long-chain alcohols.

Solution and Explanation
Step 1: Role of Hydrogen Bonding Both alcohols and phenols dissolve in water due to hydrogen bonding between the \(-OH\) group and water molecules.
Step 2: Strength of Hydrogen Bonding - Phenol has stronger hydrogen bonding due to resonance stabilization of the oxygen lone pair.
- Alcohol solubility decreases with increasing carbon chain length due to hydrophobic effects.
