B

2-methyl-2-butanol

C

2-methyl-1-butanol

D

Secondary butyl hydrogen sulphate

Answer

2-methyl-2-butanol

Explanation

Solution

CH3C⥂H2=C∣−CH2−CH32−methyl-1-butane+H2O→H2SO4Markownikoff’s rule\begin{matrix} CH_{3} \\ C ⥂ \underset{2 - \text{methyl-1-butane}}{H_{2} = \overset{|}{C} - CH_{2} - CH_{3}} + H_{2}O\underset{\text{Markownikoff's rule}}{\overset{\quad H_{2}SO_{4}\quad}{\rightarrow}} \end{matrix}
