Assertion: Aryl halides are highly reactive towards nucleophilic substitution reactions.
Reason: In case of halorenes, halogen atom is attached to sp hybridised carbon atom.

Options

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

Explanation

To solve the question regarding the assertion and reason about aryl halides and their reactivity towards nucleophilic substitution reactions, we can break it down step by step:

### Step 1: Analyze the Assertion
The assertion states that "Aryl halides are highly reactive towards nucleophilic substitution reactions."

- **Explanation**: Aryl halides, such as chlorobenzene, do not readily undergo nucleophilic substitution reactions. The presence of the aromatic ring stabilizes the molecule, making the carbon-halogen bond less reactive. Therefore, this assertion is **false**.

### Step 2: Analyze the Reason
The reason states that "In case of haloarenes, the halogen atom is attached to sp hybridized carbon atom."

- **Explanation**: In haloarenes, the carbon atom to which the halogen is attached is part of an aromatic system, which means it is sp² hybridized (not sp hybridized). The sp² hybridization arises because the carbon is bonded to two other carbons in the aromatic ring and has a double bond character with the halogen due to resonance. Thus, this reason is also **false**.

### Step 3: Conclusion
Since both the assertion and the reason are false, the correct answer to the question is that both the assertion and reason are incorrect.

### Final Answer
Both assertion and reason are false.
