22) Which of the following statement(s) is (are) TRUE? a. Zaitsev's rule: If substrate is a tertiary alkyl halide and the base is a bulky base, the mechanism proceeds via E2 reaction but this time the less substituted (less stable alkene) is the major product. b. Zaitsev's rule: If the substrate is a tertiary alkyl halide and the base is small, E2 mechanism prevails but the alkene formed is a more stable alkene (the more substituents an alkene has, the more stable it is. c. Exception to Zaitsev's rule: If substrate is a tertiary alkyl halide and the base is a bulky base, the mechanism proceeds via E2 reaction but this time the more substituted (less stable alkene) is the major product. d. Exception to Zaitsev's rule: If substrate is a tertiary alkyl halide and the base is a bulky base, the mechanism proceeds via E2 reaction but this time the less substituted (more stable alkene) is the major product. e. Exception to Zaitsev's rule: If the substrate is a tertiary alkyl halide and the base is small, E2 mechanism prevails but the alkene formed is a more stable alkene (the more substituents an alkene has, the more stable it is.
