Compare the rate of

\mathrm{S}{\mathrm{N}^2}

reaction

\begin{array}{cccccccccccccccccccc} {C{H_3} - \mathop C\limits^{\begin{array}{cccccccccccccccccccc} O \\ {||} \end{array}} - C{H_2} - Br}&{C{H_3} - Br}&{C{H_3} - \mathop C\limits^{\begin{array}{cccccccccccccccccccc} O \\ {||} \end{array}} - C{H_2} - Cl}&{C{H_3} - Cl} \\ {(1)}&{(2)}&{(3)}&{(4)} \end{array}

View answer and explanation

Correct option: C

1>3>2>4

Option D is correct because the rate of SN2 reaction depends on steric hindrance and the electronic effects of substituents, leading to the order 1 > 3 > 2 > 4.
