The only alcohol that can be prepared by the direct hydration of alkene is

Options

A. ethyl alcohol
B. propyl alcohol
C. isobutyl alcohol
D. methyl alcohol

Answer

A

Explanation

`CH_(2) = CH_(2) overset(H_(2)O //H^(+))rarr underset("Ethyl alcohol")(CH_(3)CH_(2)OH)`
`CH_(3)CH =CH_(2) overset(H_(2)O // H^(+))rarr underset("Isopropyl alcohol") overset(OH)overset(|)(CH_(3)CHCH_(3))`
`CH_(3)underset(CH_(3))underset(|)(C)=CH_(2) overset(H_(2)O // H^(+))rarr underset("t-Butyl alcohol")overset(OH)overset(|)underset(CH_(3))underset(|)(CH_(3)C CH_(3))`
Methyl alcohol can't be synthesized by direct hydration of an alkene as it contans just one carbon atom. Direct hydration of propene yields isopropyl alcohol (Markovnikov's orientation)
Ethanol is the only primary alcohol taht can be synthesized by direct hydrationn of alkene.
