The correct option is B Propan-2-ol
Since propene is an unsymmetrical alkene, the given hydration reaction takes place in accordance to Markovnikov’s rule, to form propan-2-ol. The double bond is broken and the OH group attaches at the second carbon.
The reaction is as follow:
CH3CH=CH2+H2Odil. H2SO4−−−−−−→CH3CH(OH)CH3
