Solution
\[\begin{array}{cc}
\ce{\underset{\text{Propene}}{HC3 - CH = CH2 + H - Br}-> H3C - CH - CH3 + \underset{\text{Silver nitrite}}{Ag - O - N = O} ->\underset{\text{2-Nitropropane}}{(CH3)2CH - NO2}}\\
|\phantom{}\\
\ce{\phantom{..}\underset{\text{2-Bromopropane(Major)}}{Br}\phantom{.}}
\end{array}\]
