Explain why benzyl bromide and allyl bromide cannot

Solution 11P

Step 1 of 3

Benzyl bromide and allyl bromide cannot undergo either E1 or E2 because the second step of the E1 elimination reaction requires a  proton of the carbon atom adjacent to carbon atom having leaving group to form an alkene. The single concerted process of elimination reaction requires a proton to get removed by a base thus allow leaving group to get eliminate. Benzyl bromide does not contain required removable proton to form an elimination product, an alkene. Allyl bromide also does not contain required removable proton to form an elimination product, an alkene.
