Which intermediate is formed in the acid−catalyzed dehydration of n−propyl alcohol?
Correct answer: A. CH3C+HCH3
- A. CH3C+HCH3
- B. CH3-CH2-CH3
- C. CH3CH2CH2-
- D. CH3CH2CH2+
Explanation
Dehydration of n-propyl alcohol first forms a primary carbocation (CH₃CH₂CH₂⁺), which rearranges to the more stable secondary carbocation (CH₃CH⁺CH₃)

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.
