1. (a)** 2-Bromobutane is a chiral compound. Draw the two optical isomers of this compound.
2. (b) Based on one of the structures in part (a)**, draw the product(s) that occur when this optical isomer reacts with hydroxide ions via an SN1 mechanism.
3. (c)** Using the same structures, draw the product(s) that occur when this optical isomer reacts with hydroxide ions via an SN2 mechanism.
4. (d) Use your answers to parts (b) and (c)** to explain how a polarimeter could be used to determine if the optical isomer reacts via an SN1 or SN2 mechanism.
