Which bond will break when electrophile attacks an alcohol?
Correct answer: A. O - H
- A. O - H
- B. C - O
- C. Both A and B
- D. None of these
Explanation
Which bond breaks depends on the nature of the attacking reagent. If a nucleophile attacks C-O bond will break, and if an electrophile attacks the O-H bond will break. Since the question says an electrophile is attacking so, A option O-H is our correct answer.

About Alcohols
Alcohols contain a hydroxyl group attached to a saturated carbon atom and are classified as primary, secondary or tertiary. Their nomenclature, hydrogen bonding, acidity, oxidation, dehydration, reaction with sodium and conversion to haloalkanes are covered, along with the distinction between alcohols and phenols, where the hydroxyl group is attached directly to an aromatic ring.
