Question

Show how would you synthesise the following alcohols from appropriate alkenes?

(i)

(ii)

(iii)

(iv)

Answer 1

The given alcohols can be synthesized by applying Markovnikov’s rule of acid-catalyzed hydration of appropriate alkenes.

(i)

(ii)

(iii)

Acid-catalyzed hydration of pent-2-ene also produces pentan-2-ol but along with pentan-3-ol.

Thus, the first reaction is preferred over the second one to get pentan-2-ol.
