Solution 1
\[\ce{\underset{1-Bromopropane}{CH3CH2CH2Br} ->[Alc{.} KOH, \Delta][Dehydrohalogenation] \underset{Propene}{CH3CH = CH2} ->[HBr] \underset{2-bromopropane}{CH3 - CHBrCH3}}\]
Solution 2
\[\begin{array}{cc}
\ce{\underset{1-Bromopropane}{CH3CH2CH2Br} ->[C2H5\overset{\ominus}{O}/KOH][\Delta] CH3CH = CH2 ->[HBr] CH3 - CH - CH3}\\
