Answer 1

$\text{Conversion of propene to}1\text{-bromopropane}$

This is anti-markovnikov addition reaction.

$\underset{Propene}{\underset{}{C{H}_3-CH=C{H}_2}}\stackrel{HBr/peroxide}{\to }\underset{1-Bromopropane}{\underset{}{C{H}_3-C{H}_2-C{H}_2-Br}}$

$\text{Conversion of}1\text{-bromopropane to propan-}1\text{-ol}$

This is nucleophilic substitution reaction.

$\underset{1-Bromopropane}{\underset{}{C{H}_3-C{H}_2-C{H}_2-Br}}\stackrel{sq.KOH/\Delta }{\to }\underset{Propan-1-ol}{\underset{}{C{H}_3-C{H}_2-C{H}_2-OH}}$
