3-Bromocyclohexene is a secondary halide, and benzyl bromide is a primary halide. Both halides undergo SN1 substitution about as fast as most tertiary halides. Use resonance structures to explain this enhanced reactivity.
Nucleophilic aromatic substitution involves the formation of a resonance-stabilized carbanion intermediate
called a Meisenheimer complex as the nucleophile attacks the ring carbon carrying the eventual leaving
group; electron-withdrawing groups ortho and/or para to the site of attack help to stabilize this structure
via resonance.
For the reaction below, draw the structure of the stabilized reaction intermediate in the box below.

• You do not have to consider stereochemistry.
• Draw the Meisenheimer complex with a formal charge of 0 on the nucleophilic atom. If more than
one resonance structure is possible, only draw the most important one.
In the presence of excess base and excess halogen, a methyl ketone is converted to a carboxylate ion. The reaction is known as the haloform reaction because one of the products is haloform (chloroform, bromoform, or iodoform). Before spectroscopy became a routine analytical tool, the haloform reaction served as a test for methyl ketones: the formation of iodoform, a bright yellow compound, signaled that a methyl ketone was present. Why do only methyl ketones form a haloform?

Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed.
