E1 and E2 Mechanism

E1 and E2 Mechanism in Details

The elimination reactions mainly involve three mechanism E1,E2 and E1cB. If the leaving group departs before beta -proton ( H^Theta ion) then it is E1 mechanism. If proton is taken off first before leaving group it is E1cB mechanism.The pure E2 involves both beta -Hydrogen and leaving group departing simutaneously. If acidity of beta -Hydrogen increases and leaving group ability decreases then E1cB mechanism increases. Product P is

The elimination reactions mainly involve three mechanism E1,E2 and E1cB. If the leaving group departs before beta -proton ( H^t=Theta ion) then it is E1 mechanism. If proton is taken off first before leaving group it is E1cB mechanism.The pure E2 involves both beta -Hydrogen and leaving group departing simutaneously. If acidity of beta -Hydrogen increases and leaving group ability decreases then E1cB mechanism increases. Which of the following substrate will undergo fastest reaction through E1cB route
