Which of the following is more reactive where O-H bonds break:
Correct answer: A. P° alcohol
- A. P° alcohol
- B. T° alcohol
- C. S° alcohol
- D. Cannot be predicated
Explanation
Option A is correct. Primary (P°) alcohols are more reactive where the O-H bonds break because the steric hindrance around the carbon atom that is bonded to the hydroxyl group is the least. This means that the hydrogen atom on the hydroxyl group is more easily removed.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
