Which of the following process do not yield alcohols?

(a) Acid catalysed hydration of alkenes

(b) Hydroboration-oxidation of alkenes

(d) Free radical halogenation of alkanes

I have been asked this question during a job interview.

The doubt is from Alcohols and Phenols topic in section Alcohols, Phenols and Ethers of Chemistry – Class 12

Best answer
Right answer is (d) Free radical halogenation of alkanes

The explanation is: Alkanes on free radical halogenation produce a mixture of haloalkanes and not alcohols. Alcohols can be prepared from alkenes by acid catalysed hydration and hydroboration-oxidation or from reduction of aldehydes.
