Answer 2

Hello dear,

Acid catalyzed hydration of alkenes takes place by Markonicov's rule. Thus propene gives propan-2-ol on acid catalysed hydration.
CH3-CH=CH2 + H2O --> CH3-CH(OH)-CH3

◆ Propene to propan-1-ol -
Propene is first treated with HBr/peroxide to give bromopropane which on hydroxylation by aq.KOH gives propanol.
CH3-CH=CH2 + HBr --> CH3-CH2-CH2-Br
CH3-CH2-CH2-Br + KOH --> CH3-CH2-CH2-OH + KBr



Hope this helped you. Thanks for asking..
