Solution
\[\begin{array}{cc}
\ce{CH3 - \underset{\text{But-1-ene}}{CH2 - CH} = CH2 + \underset{\text{(Cold conc.)}}{H - OSO3H}->[Markownikov addition] CH3 - CH2 - CH - CH3}\\
\phantom{...............................................................}|\\
\phantom{.....................................................................}\ce{OSO3H}\end{array}\]
\[\begin{array}{cc}
\ce{CH3 - CH2 - CH - CH3 + H - OH->[\Delta]CH3 - CH2 - CH - CH3}\\
\phantom{.....}|\phantom{......................................}|\\
\phantom{...........}\ce{OSO3H}\phantom{..............................}\ce{\underset{\text{Butan-2-ol}}{OH}}
\end{array}\]
