Hydration of aldehydes and ketones can be catalyzed by acid
or base. Bases catalyze hydration by:
protonating the carbonyl oxygen
making the carbonyl group more electrophilic
employing hydroxide ion, which is a better nucleophile than water
making the carbonyl group less electrophilic
shifting the equilibrium position of the reaction to favor products

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.
