Electrophilic addition of bromine, Br₂, to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic
intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH₂Cl₂.

Br
In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion
to yield the product. 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.
Draw curved arrows to show the movement of electrons in this step of the mechanism.

When 2-chloro-2-methylpropane, (CH3)3CCl, reacts with aqueous sodium hydroxide, the process is not a “concerted process”; instead a reactive intermediate, (CH3)3C+, is formed as a result of the first step of the reaction mechanism.
Explain why this happens.

Imines are formed in a reversible, acid-catalyzed process that begins with nucleophilic addition of the primary amine to the carbonyl group, followed by transfer of the proton to yield a neutral carbinolamine. Protonation of the hydroxyl group converts it into a good leaving group and an E1-like loss of water yields an iminium ion. Deprotonation yields the product imine and regenerates the acid catalyst.
