The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement step by step. ### Step 1: Evaluate Statement 1 **Statement 1:** Aryl amines cannot be prepared by Gabriel's phthalimide synthesis. - **Explanation:** Gabriel's phthalimide synthesis is a method used to prepare primary amines. It involves the reaction of phthalimide with an alkyl halide to form a N-alkyl phthalimide, which is then hydrolyzed to yield the primary amine. However, this method is not suitable for preparing aryl amines because the nucleophile (the phthalimide ion) is bulky, and the reaction requires a good leaving group. Aryl halides do not react well in this synthesis due to steric hindrance and the nature of the aryl group, which does not favor the nucleophilic substitution required in this reaction. - **Conclusion:** Statement 1 is **True**. ### Step 2: Evaluate Statement 2 **Statement 2:** Aromatic halides do not give SN2 reactions. - **Explanation:** Aromatic halides (aryl halides) indeed do not undergo SN2 reactions. This is primarily due to two reasons: 1. **Steric Hindrance:** The aromatic ring creates significant steric hindrance that prevents the nucleophile from effectively attacking the carbon atom bonded to the halide. 2. **Resonance Stabilization:** The carbon-halogen bond in aryl halides has partial double bond character due to resonance. This makes the bond stronger and less reactive towards nucleophilic attack, which is a requirement for SN2 reactions. - **Conclusion:** Statement 2 is **True**. ### Step 3: Determine the Relationship Between the Statements Both statements are true, but they are independent of each other. The first statement discusses the preparation of aryl amines specifically through Gabriel's phthalimide synthesis, while the second statement discusses the reactivity of aromatic halides in SN2 reactions. ### Final Conclusion Both statements are true, but they do not have a direct relationship with each other.
