Assertion (A): Aromatic `1^@` amines can be prepared by Gabriel Phthalimide synthesis. Reason (R): Aryl halides do not undergo nucleophilic substitution with anion formed by phthalimide.

Options

A. Both A and Rare true and R is the correct explanation of A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is True

Explanation

To solve the assertion and reason question regarding the preparation of aromatic 1° amines by Gabriel Phthalimide synthesis, we will analyze both the assertion (A) and the reason (R) step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that aromatic 1° amines can be prepared by Gabriel Phthalimide synthesis.
- Gabriel Phthalimide synthesis is a method primarily used to prepare 1° amines from alkyl halides, not aryl halides.

2. **Understanding the Reason (R)**:
- The reason states that aryl halides do not undergo nucleophilic substitution with the anion formed by phthalimide.
- This is true because aryl halides are generally resistant to nucleophilic substitution due to the stability of the aromatic ring and the partial double bond character of the carbon-halogen bond.

3. **Analyzing the Mechanism of Gabriel Phthalimide Synthesis**:
- In Gabriel Phthalimide synthesis, the phthalimide is deprotonated by a base (like KOH) to form a nucleophilic anion.
- This anion can then attack an alkyl halide (R-X) in an SN2 reaction to form a 1° amine (NH2-R).
- However, if we try to use an aryl halide (Ar-X) instead of an alkyl halide, the nucleophilic substitution does not occur.

4. **Conclusion**:
- Since the assertion claims that aromatic 1° amines can be prepared via this method, and we established that this is not possible (as aryl halides do not participate in the reaction), the assertion is **false**.
- The reason provided is correct, as it accurately describes the behavior of aryl halides in nucleophilic substitution reactions.

5. **Final Answer**:
- The assertion (A) is false, and the reason (R) is true. Therefore, the correct option is option 4.
