Alkyl hydrogen sulphates can be easily hydrolyzed to alcohols by heating them with water. Which of the following alcohols can be made by this method?
(i) Isopropyl alcohol
(ii) `n`-Propyl alcohol
(iii) Isobutyl alcohol
(iv) tert-Butyl alcohol

Options

A. (i),(iii)
B. (ii),(iii)
C. (i),(iv)
D. (ii),(iv)

Answer

C

Explanation

The addition of sulphuric acid follows Markovinkov's rule. Consequently, certain alochols cannot be obtained by this method. Isopropyl alcohol can be made, but not `n`-propyl alcohol. Tert-Butyl alcohol can be made, but not isobutyl alcohol.
