WebUnimolecular elimination reaction (E1) occurs in two steps: ionisation and deprotonation. During the ionisation bond between carbon and halogen breaks, an intermediate carbocation is formed. During deprotonation, a proton is lost from carbocation. The base further forms a pi bond within the molecule. WebStart your trial now!
