3-bromocylohexene or bromocyclohexane reacts faster in E2/E1 reaction is to be identified. Concept Introduction: An E1 reaction is a two-step reaction in which the alkyl halide dissociates forming a carbocation intermediate. Then a base removes a proton from adjacent carbon to a positively charged carbon. Major product is more stable alkene . An E2 reaction is a concerted, one-step reaction in which the proton is the more stable alkene, unless the reactants are sterically hindered or the leaving group is poor.

Consider this step in a radical reaction: Br N O hv What type of step is this? Check all that apply. Draw the products of the step on the right-hand side of the drawing area below. If more than one set of products is possible, draw any set. Also, draw the mechanism arrows on the left-hand side of the drawing area to show how this happens. O primary Otermination O initialization O electrophilic O none of the above × ☑

None

Can I get a drawing of what is happening with the orbitals (particularly the p orbital) on the O in the OH group? Is the p orbital on the O involved in the ring resonance? Why or why not?
