The compound which gives the most stable ion when O-H bonds break is:
Correct answer: A. CH3CH2CH2CH2OH
- A. CH3CH2CH2CH2OH
- B. (CH3)2CHCH2OH
- C. (CH3)3COH
- D. CH3CHOHCH2CH3
Explanation
CH3CH2CH2CH2OH (1-butanol, primary) → most stable ion(CH3)2CHCH2OH (isobutanol, primary branched) → nextCH3CH(OH)CH2CH3 (2-butanol, secondary) → less stable(CH3)3COH (tert-butanol, tertiary) → least stable

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.
