Which of the following amine cannot be prepared by the Gabriel phthalimide synthesis method?
Which of the following amine cannot be prepared by the Gabriel phthalimide synthesis method?
Ethylamine
Benzylamine
Phenylamine
Propylamine
Solution
Gabriel phthalimide synthesis cannot be used for the preparation of aromatic primary amines because the $\mathrm{C}$ $\mathrm{X}$ bond in an aromatic halide (aryl halide) is stronger and thus difficult to break.
