Statement-1:Polyacylation in benzene does not occur during Friedal Craft's acylation.
Statement-2:As the product ketone is much more reactive than starting material.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Explanation

To solve the question, we need to analyze both statements regarding Friedel-Crafts acylation and determine their validity.

### Step-by-Step Solution:

1. **Understanding Friedel-Crafts Acylation**:
- Friedel-Crafts acylation is a reaction where an acyl group (RCO-) is introduced into an aromatic ring (like benzene) using an acyl chloride and a Lewis acid catalyst (like AlCl3).
- The general reaction can be represented as:
\[ \text{Benzene} + \text{RCOCl} \xrightarrow{\text{AlCl}_3} \text{Acylated Benzene} \]

2. **Analyzing Statement 1**:
- **Statement 1**: "Polyacylation in benzene does not occur during Friedel-Crafts acylation."
- Polyacylation refers to the introduction of more than one acyl group onto the benzene ring.
- In Friedel-Crafts acylation, the acyl group is an electron-withdrawing group due to the carbonyl (C=O) bond. This reduces the electron density on the aromatic ring, making it less reactive towards further electrophilic substitution.
- Therefore, polyacylation does not occur because the first acylation deactivates the ring for further substitutions.
- **Conclusion**: Statement 1 is **True**.

3. **Analyzing Statement 2**:
- **Statement 2**: "As the product ketone is much more reactive than the starting material."
- The product of Friedel-Crafts acylation is a ketone, which is indeed less reactive than benzene due to the presence of the electron-withdrawing carbonyl group.
- The ketone decreases the electron density on the aromatic ring, making it less reactive towards further electrophilic attack.
- **Conclusion**: Statement 2 is **False**.

4. **Final Evaluation**:
- Based on the analysis:
- Statement 1 is **True**.
- Statement 2 is **False**.
- The correct answer is **Option C**: Statement 1 is true and Statement 2 is false.
