**Task:**
- **Objective**: Draw the starting structure that would lead to the given polymer under radical conditions.
**Diagram:**
- **Box Section**: There is a dashed rectangular box labeled "Select to Draw," indicating the area where students should sketch the starting monomer structure.
**Reaction Conditions:**
- **Arrow Pointing Down**: Illustrates the process leading from the starting structure to the polymer.
- **Radical Initiation Conditions**:
- Δ or λν (represents heat or UV light)
- AIBN (Azobisisobutyronitrile), a radical initiator commonly used in polymerization reactions.
**Polymer Structure:**
- The chemical structure is drawn with brackets indicating repeat units, showing a carbon backbone.
- A cyano group (CN) is attached to one of the carbon atoms in the repeating unit.
- The subscript "n" denotes the number of repeating units in the polymer chain.
**Explanation:**
This exercise teaches students to identify and sketch the monomer that can form a given polymer through radical polymerization. The use of AIBN as a radical initiator highlights the importance of initiators in the formation of free radicals, which propagate the polymerization process under heat or UV light. Understanding these mechanisms is crucial in the field of polymer chemistry.
