1.1. 2-bromo-2-methylpropane is refluxed with ethanolic potassium hydroxide, KOH. The result is a mixture of products containing roughly a 4 : 1 ratio of alkene to alcohol.

i) Name the alkene and alcohol produced.

ii) Name and outline the mechanism for the production of the alkene in this reaction.

1.2. Suggest why there is a mixture of an alkene and an alcohol produced in the reaction outlined in part (a).

1.3. An iodoalkane can be prepared by the reaction between red phosphorus, P, and iodine, I₂, to produce phosphorus (III) iodide, PI₃.

This then is reacted with an alcohol to produce the iodoalkane and phosphonic acid, H₃PO₃.

Give the equation for the reaction between butan-2-ol and phosphorus (III) iodide. You do not have to include state symbols.

1.4. During the series of reactions to produce a bromoalkane a 50 : 50 mix of sulfuric acid and water is reacted with potassium bromide to produce hydrogen bromide. The mixture is kept very cool.

Explain why sulfuric acid can not be used in the preparation of an iodoalkane
