chemistry
Explanation
To solve this problem, we need to identify which polymer is thermosetting.Thermosetting polymers are materials that irreversibly cure, forming a rigid structure.Let's analyze each option:Option 1: The structure represents polyvinyl chloride (PVC), a thermoplastic polymer.Option 2: The structure represents polyvinyl chloride (PVC), a thermoplastic polymer.Option 3: The structure represents nylon, a type of polyamide, which is a thermoplastic polymer.Option 4: The structure represents Bakelite, a phenol-formaldehyde resin, which is a thermosetting polymer.Bakelite is known for its heat-resistant and electrical insulating properties.Therefore, the correct option is Option 4.
