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.

The conversion of alcohols into alkyl halides by reaction with hydrogen halides is an example of a Nucleophilic Substitution Reaction. This kind of reaction can proceed by two different mechanisms depending on the structure of alcohol substrates used. Generally, primary alcohols are substituted via SN2 mechanism, while secondary and tertiary alcohols undergo SN1 mechanism. Consider the following reaction given in the picture below and the questions in the picture too.

Which of the statements below is true regarding the reactivity of benzene?   a.   Substitution is preferred over elimination reaction to maintain benzene’s aromaticity.   b.     Being rich in electron, benzene acts as an electrophile in a substitution reaction.   c.     Because of loosely held ∏ electrons, benzene is less reactive than alkene.   d. The presence of an acid catalyst is added in order to enhance benzene’s electrophilicity.

CH=CH₂ CH=CH₂ CH3O O₂N A B Which will be true about the reaction of the two alkenes with HBr? Select the correct response(s): Compound A is more reactive than compound B. CH3O- increases the reactivity of the alkene. N₂O- cause electrons to flow into the ring. CH3O- removes electrons from the ring. Compound B is more reactive than compound A. CH3O- decreases the reactivity of the alkene. and
