What does it act as?
Base (proton accepter)
3 of 6
What happens?
The hydroxide ion bonds the the H atom next to the halogen. Electrons move from the Hydrogen atom to form a double bond. Newly formed double bond repulses e- in carbon-X bond onto halogen so eliminated as -ve halide ion

Overall eqn:
CH3CHBrCH3+OH-= CH3CH=CH2+Br-+H2O

How do you favour elimination?
