$i > ii > iii$

Vedclass · Answer

(A) The reactivity of an $E_2$ reaction depends on the stability of the transition state,which is influenced by the stability of the resulting alkene.$(i)$ In the first case,the elimination leads to a conjugated diene system,which is highly stable.(ii) In the second case,the elimination leads to a more substituted alkene within the bicyclic system.(iii) In the third case,the elimination leads to a less substituted alkene compared to (ii).Therefore,the order of reactivity is $(i) > (ii) > (iii)$.

The correct reactivity order for $E_2$ reaction with alcoholic $KOH$ will be:
$(i)$ $3-$chlorocyclohexene derivative (conjugated system)
(ii) $1-$chlorodecalin derivative (with double bond)
(iii) $1-$chlorodecalin (saturated)
