2-bromo-2-methylpropane reacts with aqueous sodium hydroxide to form 2-methylpropan-2-ol. Explain the mechanism of this reaction, including the inductive effect of the alkyl groups and the reason for the stability of the intermediate.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Explain means: Give the reasons or the mechanism: why or how something happens. Link each point to the next with because, so or which means. A list of facts with no links usually loses the reasoning marks.
