$a > b > c$

Vedclass · Answer

(B) The rate of an $E_2$ reaction depends on the stability of the transition state,which is influenced by the degree of substitution of the alkyl halide.For $E_2$ reactions,the order of reactivity is generally $3^\circ > 2^\circ > 1^\circ$ because the transition state for more substituted alkenes is more stable due to hyperconjugation and inductive effects.Compound $a$ is a tertiary $(3^\circ)$ alkyl halide,compound $b$ is a secondary $(2^\circ)$ alkyl halide,and compound $c$ is a primary $(1^\circ)$ alkyl halide.Therefore,the order of reactivity is $a > b > c$.

Compare the rate of $E_2$ reaction for the following compounds:
$a$: $(CH_3)_3C-Br$
$b$: $CH_3-CH(Br)-CH_3$
$c$: $CH_3-CH_2-Br$
