Differentiate between the following pairs of polymer based on the property mentioned against each :
Novolac and Bakelite (Structure)

Explanation

To differentiate between Novolac and Bakelite based on their structures, let's analyze each polymer step by step.

### Step 1: Understanding Novolac Structure
- **Novolac** is a type of phenolic resin that is characterized by its **linear structure**.
- In its structure, the polymer chains consist of repeating units that are connected in a straight chain without any branching or cross-linking.
- The basic structure of Novolac can be represented as follows:
- It consists of phenolic units connected by methylene (–CH2–) linkages.
- The general representation includes hydroxyl (–OH) groups attached to the aromatic rings.
