Explain the reason for the following:
Tertiary butyl iodide forms tertiary butyl alcohol with water, but with an alkali solution, it yields isobutylene (2-methyl propene).

Solution

Tertiary butyl iodide forms tertiary butyl alcohol with water due to S_N1 mechanism. This reaction is carried out in polar solvents like water and alcohol. The reaction between tert-butyl iodide and hydroxide ion yields tert-butyl alcohol.In the case of alkali, solvent racemisation takes place. Due to the racemisation, the attack of the nucleophile may be accomplished from either side resulting in a mixture of the product. Hence isobutylene is formed.
