1. a Explain the mechanism for the reaction of the tertiary halogenoalkane 2-bromo-2-methylpropane with aqueous sodium hydroxide. Use curly arrows to show the movement of the electrons.
2. b Draw an energy profile diagram for the reaction. Include a drawing of the carbocation formed during the reaction.
3. c** Why is the carbocation formed during the reaction described as an *intermediate* rather than as a *transition state*?
4. d** Describe the shape and bond angles of the carbocation.
5. e** The mechanism for this reaction is known as SN1 . What does the 1 represent?
6. f** Give the rate equation for the reaction.
