Question

In a $	ext{S}_	ext{N}2$ substitution reaction of the type$$	ext{R}-	ext{Br} + 	ext{Cl}^- \xrightarrow{	ext{DMF}} 	ext{R}-	ext{Cl} + 	ext{Br}^-$$Which one of the following has the highest relative rate?

Accepted Answer

$	ext{CH}_3	ext{CH}_2	ext{Br}$

Answer

CH₃—CH₂—CH₂Br

Answer

$	ext{CH}_3-\underset{\substack{| \ 	ext{CH}_3}}{	ext{CH}}-	ext{CH}_2	ext{Br}$

Answer

$	ext{CH}_3-\overset{\substack{	ext{CH}_3 \ |}}{\underset{\substack{| \ 	ext{CH}_3}}{	ext{C}}}-	ext{CH}_2	ext{Br}$
