Assertion (A) Like bromination of benzene, bromination of phenol is also carried out in the presence of Lewis acid.
Reason (R) Lewis acid polarises the bromine molecule.

Options

A. Assertion and reason both are correct and reason is correct explanation of assertion.
B. Assertion and reason both are wrong statements.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statement.

Explanation

To solve the question, we need to analyze both the assertion (A) and the reason (R) provided in the question.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Like bromination of benzene, bromination of phenol is also carried out in the presence of Lewis acid."
- In the case of benzene, bromination typically requires a Lewis acid (like FeBr3 or AlBr3) to act as a catalyst. This is because the Lewis acid helps to generate a more electrophilic bromine species, which can then react with the benzene ring.

2. **Understanding the Reason (R)**:
- The reason states that "Lewis acid polarizes the bromine molecule."
- This is true; the Lewis acid interacts with the bromine molecule, causing polarization. This polarization makes one of the bromine atoms more electrophilic, facilitating the electrophilic aromatic substitution reaction with the benzene or phenol.

3. **Bromination of Phenol**:
- Phenol can also undergo bromination, but it is more reactive than benzene due to the presence of the hydroxyl (-OH) group, which is an activating group.
- The -OH group donates electron density to the benzene ring, making it more susceptible to electrophilic attack. This means that while bromination of phenol can occur in the presence of a Lewis acid, it is not strictly necessary due to the activating effect of the -OH group.

4. **Conclusion**:
- The assertion is incorrect because bromination of phenol does not strictly require a Lewis acid, while the reason is correct as the Lewis acid does polarize the bromine molecule.
- Therefore, the correct answer is that the assertion is false, but the reason is true.

### Final Answer:
- Assertion (A) is incorrect.
- Reason (R) is correct.
- The correct option is that the assertion is wrong, but the reason is correct.
