Why is the alkyl bromide substrate below not capable of undergoing an E2 elimination reaction upon treatment with potassium hydroxide (KOH) in ethanol (EtOH)?   -Br– is too poor a leaving group. -Too much angle strain would be present in the alkene product. -Potassium hydroxide is a poor base to use in E2 reactions. -An anti-periplanar E2 elimination cannot occur due to the lack of a beta-hydrogen in the substrate
