Draw all four possible isomers.What is the substitution reaction mechanism used to yield 7-chloro-4-ethylhept-2-ene? Please draw it out with all steps and arrows.A benzene ring alters the reactivity of a neighboring group in the so-called “benzylic” position, similarly to how a double bond alters the reactivity of groups in the “allylic” position. Benzylic cations, anions, and radicals are all more stable than simple alkyl intermediates. a) Use resonance structures to show the delocalization of the positive charge, negative charge, and unpaired electron of the benzyl cation, anion, and radical.
