Which statement correctly describes E2 reactions of alkyl halides? Question 13 options: The rate of the E2 reaction depends only on the concentration of the alkyl halide. The rate of the E2 reaction depends only on the concentration of the base. The ? C-H bond and the C-halogen bond are broken in the same step. Alkyl bromides generally react faster than alkyl iodides.
