There are two alkyl halides; 2-chloro-2-methylpropane and 2-bromo-2-methylpropane. Use water and NaOH with each of the three solvents ( isopropyl, acetone, and ethanol) in individual reactions with the alkyl halides.

1. Write a balanced SN1 chemical equation between each alkyl halide and the best nucleophile in solution.

2. Write a balanced SN2 chemical equation between each alkyl halide and the best nucleophile in solution.

3. Write a balanced E1 chemical equation for each halide and the base(s) in solution.

4. Write a balanced E2 chemical equation for each halide and the base in solution.
