The correct Answer is:
To analyze the statements provided, we will evaluate each statement one by one. ### Step 1: Evaluate Statement 1 **Statement 1:** Acetophenone gives aldol condensation. **Solution:** Acetophenone has the structure of a ketone with a phenyl group attached to the carbonyl carbon. The structure can be represented as follows: \[ \text{C}_6\text{H}_5\text{C(=O)CH}_3 \] For aldol condensation to occur, the compound must have alpha-hydrogens adjacent to the carbonyl group. In acetophenone, there are three alpha-hydrogens on the methyl group (CH₃) adjacent to the carbonyl (C=O). Therefore, acetophenone can undergo aldol condensation. **Conclusion:** Statement 1 is **True**. ### Step 2: Evaluate Statement 2 **Statement 2:** Benzaldehyde is more reactive than acetaldehyde towards nucleophilic addition. **Solution:** Benzaldehyde has the structure: \[ \text{C}_6\text{H}_5\text{CHO} \] Acetaldehyde has the structure: \[ \text{CH}_3\text{CHO} \] In nucleophilic addition reactions, the reactivity is influenced by the presence of electron-donating or electron-withdrawing groups. The phenyl group in benzaldehyde is electron-withdrawing due to resonance, which decreases the electron density on the carbonyl carbon, making it less reactive towards nucleophiles. In contrast, acetaldehyde has no such electron-withdrawing group and is therefore more reactive towards nucleophilic addition. **Conclusion:** Statement 2 is **False**. ### Step 3: Evaluate Statement 3 **Statement 3:** Benzophenone has alpha-hydrogens. **Solution:** Benzophenone has the structure: \[ \text{C}_6\text{H}_5\text{C(=O)C}_6\text{H}_5 \] In this structure, the carbonyl carbon is bonded to two phenyl groups. There are no hydrogen atoms attached to the carbons adjacent to the carbonyl group (there are no alpha-hydrogens). Therefore, benzophenone does not have any alpha-hydrogens. **Conclusion:** Statement 3 is **False**. ### Final Summary: - Statement 1: **True** - Statement 2: **False** - Statement 3: **False**
