Assertion : Addition reaction of water to but1 -ene in acidic medium yields butan-2-ol. Reason : Addition of water in acidic medium proceeds through the formation of primary carbocation.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.

Isobutylene on hydroboration followed by oxidation with hydrogen peroxide in presence of base yields
1 n-butyl alcohol
2 sec-butyl alcohol
3 tert-butyl alcohol
4 isobutyl alcohol
Explanation:
Isobutylene on hydroboration followed by oxidation with hydrogen peroxide in presence of base yields isobutyl alcohol. Note: The alcohol formed is in accordance to anti-Markovnikov's rule.

Incorrect method of preparation of alcohols from the following is
1 reaction of ketone with RMgBr followed by hydrolysis
2 reaction of alkyl halide with aqueous NaOH .
3 ozonolysis of alkene
4 hydroboration-oxidation of alkene
Explanation:
Ozonolysis of alkenes does not produce alcohols, instead it gives aldehyde, ketone & carboxylic acid. Rest of the given reactions produce alcohols.
