उत्तर
Both Statement I and Statement II are true.
Explanation:
The positive charge on nitrogen is powerfully electron-withdrawing, which deactivates the ring for further acylation or alkylation reactions. Consequently, aniline does not undergo Friedel-Craft alkylation.
Phthalimide does not undergo nucleophilic substitution with aryl halides. Therefore, it is impossible to synthesise aniline through Gabriel phthalimide synthesis.
Therefore both the statements are correct.
