BRAINCAKEMechanism of Elimination
The elimination mechanism is shown with three curly arrows. The hydroxide ion acts as a base and removes a proton from the carbon atom next to the carbon bonded to the halogen.
The first curly arrow goes from a lone pair on the hydroxide ion to a hydrogen atom on the adjacent carbon. The hydroxide ion becomes a water molecule.
