Question

Out of the following alkenes, the one which will produce tertiary butyl alcohol on acid catalysed hydration is:

Options

• \[\ce{CH3CH2CH = CH2}\]

• \[\ce{CH3CH = CH2}\]

• \[\ce{CH3 - CH = CH - CH3}\]

• \[\ce{(CH3)2C = CH2}\]

Answer 1

\[\ce{(CH3)2C = CH2}\]

Explanation:

Substituted alkenes undergo acidic hydrolysis, producing a tertiary alcohol via Markownikoff's addition. The negative half of the addition goes to the carbon atom with the fewest hydrogen atoms.
