Vedclass · Answer

(B) The reactivity of alkyl halides towards the $E_2$ mechanism depends on the stability of the transition state and steric hindrance.For $E_2$ reactions,the order of reactivity is generally $3^\circ > 2^\circ > 1^\circ$ alkyl halides.However,in the given options,we must consider the structure of the $\beta$-carbon.Option $B$ is a $2^\circ$ alkyl halide,which is more reactive than the $1^\circ$ alkyl halides provided in $A$,$C$,and $D$.Therefore,$CH_3CH_2CH(Br)CH_3$ is the most reactive towards the $E_2$ mechanism among the choices.
