Question

The major product of the following reaction is:

\[\begin{array}{cc}
\ce{Cl}\phantom{.........................}\\
|\phantom{..........................}\\
\ce{CH3 - CH - CH3 ->[(i) Alc. KOH][(ii) HBr/peroxide (iii) aq. KOH]}
\end{array}\]

विकल्प

• \[\begin{array}{cc}
  \phantom{.}\ce{OH}\\
  |\phantom{..}\\
  \ce{CH3 - CH - CH3}
  \end{array}\]

• CH₃ – CH₂ – CH₂ – OH

• CH₃CH = CH₂

• \[\begin{array}{cc}
  \ce{Br}\\
  |\phantom{..}\\
  \ce{CH3 - CH - CH3}
  \end{array}\]

Answer 1

CH₃ – CH₂ – CH₂ – OH

Explanation:

\[\begin{array}{cc}
\ce{Cl}\phantom{..........................................................................................}\\
|\phantom{...........................................................................................}\\
\ce{\underset{2-chloropropane}{CH3 - CH - CH3} ->[alc. KOH][Heat] \underset{Propene}{CH3CH=CH2} ->[HBr][Peroxide] \underset{1-Bromopropane}{CH3 - CH2 - CH2 - Br} ->[aq. KOH] \underset{\underset{(Major)}{propan-1-ol}}{CH3 - CH2 - CH2 - OH}}
\end{array}\]
