Worked practice questions

**Phenol** differs from an alcohol because:

  1. Phenol's OH is bonded to an sp² carbon of an aromatic ring
  2. Phenol's OH is bonded to an sp³ carbon
  3. Phenol has no OH group
  4. Both phenol and alcohol have OH on aromatic rings
Show answer and solution

Correct answer: A. Phenol's OH is bonded to an sp² carbon of an aromatic ring

**Phenols:** -OH bonded directly to an aromatic-ring carbon (sp²). **Alcohols:** -OH on aliphatic sp³ carbon. **Crucial difference:** phenol's lone pair conjugates with ring ⇒ acidic; alcohol is essentially neutral.
