Question

The given compound can be synthesized by a $S_{N}2$ reaction. Select both the haloalkane and nucleophile that will give the product.

${CH}_{3}SH$.

• A. $C{H}_{3}Cl$
• B. $H^{-}$
• C. $C{H}_2\left(SH\right)Cl$
• D. $S{H}^{-}$

Answer 1

Answer: (A), (D)

$C{H}_{3}Cl$
$S{H}^{-}$

${CH}_{3}SH$ can be synthesized by the combination of halo alkane ${CH}_{3}Cl$ and nucleophile $H{S}^{-}$.

${CH}_{3}Cl+H{S}^{-}\to {CH}_{3}SH+C{l}^{-}$

In this reaction, the chloride ion of methyl chloride is displaced with $-S{H}^{-}$ group.
