(b)
Interpretation:
Structural formula for the alcohol formed by acid-catalyzed hydration of the given alkene should be determined.
Concept Introduction:
According to Markovnikov’s rule, in acid-catalyzed hydration of alkenes, H of H2 O adds to the carbon of the double bond with greater number of hydrogen atoms and OH of H2 O adds to the carbon with smaller number of hydrogen atoms.
