Phenol is more reactive than benzene towards electrophilic substitution reaction.
In case of Phenol, the intermediate carbocation is more resonance stabilised.

Options

A. if both assertion and reason are true and reason is thr correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reson are false.

Explanation

To solve the assertion and reason question regarding the reactivity of phenol compared to benzene in electrophilic substitution reactions, we can break down the solution into clear steps:

### Step 1: Understand the Assertion
The assertion states that "Phenol is more reactive than benzene towards electrophilic substitution reactions."

**Solution:** This statement is true. Phenol is indeed more reactive than benzene in electrophilic substitution reactions due to the presence of the hydroxyl (-OH) group, which is an activating group. The -OH group increases the electron density on the aromatic ring, making it more susceptible to electrophilic attack.

**Hint:** Remember that activating groups increase the reactivity of aromatic compounds by donating electron density to the ring.

### Step 2: Understand the Reason
The reason provided is that "in case of phenol, the intermediate carbocation is more resonance stabilized."

**Solution:** This statement is partially true. When an electrophile attacks phenol, it forms a carbocation intermediate. The -OH group can stabilize this carbocation through resonance, allowing the positive charge to be delocalized over the aromatic ring. However, the assertion about the intermediate being "more resonance stabilized" is misleading because while phenol does stabilize the intermediate, the comparison to benzene is not straightforward. Benzene itself does not have a -OH group, and thus does not have the same resonance stabilization in the presence of an electrophile.

**Hint:** Consider how resonance structures contribute to the stability of intermediates in electrophilic substitution reactions.

### Step 3: Conclusion
Based on the evaluation of both statements, we can conclude that:
- The assertion is true: Phenol is more reactive than benzene.
- The reason is misleading: While the carbocation in phenol is resonance stabilized, the comparison to benzene's stability is not directly applicable.

### Final Answer
The correct answer is option C: The assertion is true, but the reason is false.
