Question

Which of the following is an example of S_N2 reaction?

Options

• \[\ce{CH3Br + OH^- -> CH3OH + Br^-}\]

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

• \[\ce{CH3CH2OH ->[-H2O] CH2 = CH2}\]

• \[\ce{(CH3)3C-Br + OH^- -> (CH3)3COH + Br^-}\]

Answer 1

\[\ce{CH3Br + OH^- -> CH3OH + Br^-}\]
