Aromatic primary amines cannot be prepared by Gabriel phthalimide synthesis because :

1. Alkyl halides do not undergo electrophilic substitution with the anion formed by the phthalimide
2. Alkyl halides do not undergo nucleophilic substitution with the anion formed by the phthalimide
3. Aryl halides do not undergo nucleophilic substitution with the anion formed by the phthalimide
4. Aryl halides do not undergo electrophilic substitution with the anion formed by the phthalimide
