How will you bring about the following conversion?
1-bromopropane to 2-bromopropane
Answer
Answer
AIEquations: $\mathrm{CH_{3}CH_{2}CH_{2}Br} + \mathrm{KOH} \xrightarrow{\text{alc.}\text{ }\text{KOH}\text{,}\text{ }\text{heat}} \mathrm{CH_{3}CH=CH_{2}} + \mathrm{KBr} + \mathrm{H_{2}O}$ $\mathrm{CH_{3}CH=CH_{2}} + \mathrm{HBr} \longrightarrow \mathrm{CH_{3}CHBrCH_{3}}$
1-Bromopropane to 2-bromopropane: dehydrohalogenation, then Markovnikov addition of HBr.
