(a) Draw structures for all organic products that would result when an excess of cis-1,3-dimethylcyclohexane reacts with Br₂ in the presence of heat and light. Use three-dimensional formulas to show stereochemistry.

(b) Draw structures for all organic products that would result when an excess of cis-1,3-dimethylcyclohexane reacts with Cl₂ in the presence of heat and light. Use three-dimensional formulas to show stereochemistry.

(c) As an alternative, use cis-1,2-dimethylcyclohexane to answer parts (a) and (b) above.
