Acid catalyzed hydration of alkenes except ethene leads to the formation of

1. primary alcohol
2. secondary or tertiary alcohol
3. mixture of primary and secondary alcohols
4. mixture of secondary and tertiary alcohols

Correct answer: secondary or tertiary alcohol

Solution

Acid-catalyzed hydration follows Markovnikov's rule, placing OH on the more substituted carbon, so for alkenes other than ethene it yields secondary or tertiary alcohols. Stored answer 'primary alcohol' is wrong; the correct answer is secondary or tertiary alcohol.
