A: Phenol and formaldehyde are momers of Bakelite.
R: Bakelite is used for making combs.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark 1.
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark 2.
C. If Assertion is true statement but Reason is false, then mark 3.
D. If both Assertion and Reason are false statements the mark 4.

Answer

To analyze the statements provided in the question, we will break it down into two parts: the assertion (A) and the reason (R).

### Step 1: Evaluate the Assertion (A)
The assertion states that "Phenol and formaldehyde are the monomers of Bakelite."

- **Understanding Bakelite**: Bakelite is a type of thermosetting plastic that is formed through a polymerization process involving phenol and formaldehyde.
- **Monomer Identification**: In the synthesis of Bakelite, phenol (C6H5OH) and formaldehyde (HCHO) undergo a condensation reaction. This reaction involves the combination of these two monomers to form a polymer while releasing water as a byproduct.
- **Conclusion on Assertion**: Since phenol and formaldehyde are indeed the monomers used to produce Bakelite, the assertion is **True**.

### Step 2: Evaluate the Reason (R)
The reason states that "Bakelite is used for making combs."

- **Application of Bakelite**: Bakelite is known for its durability and heat resistance, making it suitable for various applications, including electrical insulators, kitchenware, and combs.
- **Conclusion on Reason**: The statement that Bakelite is used for making combs is also **True**.

### Step 3: Determine the Relationship Between A and R
- The assertion is correct, and the reason is also correct. However, the reason does not provide a direct explanation for the assertion. The assertion discusses the monomers of Bakelite, while the reason discusses one of its applications.
- Therefore, while both statements are true, the reason is not the correct explanation for the assertion.

### Final Conclusion
- **Assertion (A)**: True
- **Reason (R)**: True
- The correct relationship is that both statements are true, but R is not the correct explanation for A.
