Assertion (A)Assertion (A) Glyptal is a copolymer.
Reason(R )Network polymers have high molecular mass.

Options

A. Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion
C. Assertion is correct but Reason is incorrect
D. Assertion is incorrect and Reason is correct

Answer

To solve the assertion-reason question, we will analyze both the assertion and the reason step by step.

### Step 1: Analyze the Assertion
- **Assertion (A)**: Glyptal is a copolymer.
- A copolymer is a polymer made from two different types of monomers.
- Glyptal is synthesized from two monomers: Ethylene Glycol and Phthalic Acid.
- Therefore, Glyptal is indeed a copolymer.

### Step 2: Analyze the Reason
- **Reason (R)**: Network polymers have high molecular mass.
- Network polymers are characterized by their three-dimensional structures formed by cross-linking of polymer chains.
- These polymers typically have high molecular masses due to the extensive bonding between chains.
- Thus, the statement that network polymers have high molecular mass is correct.

### Step 3: Determine the Relationship
- Both the assertion and the reason are true statements.
- However, the reason provided does not explain why Glyptal is a copolymer. The fact that network polymers have high molecular mass does not relate to the definition or characteristics of Glyptal as a copolymer.

### Conclusion
- Since both the assertion and reason are true but the reason is not the correct explanation for the assertion, the correct answer is:
- **Option B**: Both assertion and reason are correct, but reason is not the correct explanation of assertion.
