Question

The best method for preparing primary amines from alkyl halides without changing the number of carbon atoms in the chain is:

• A. Hofmann bromamide reaction
• B. Gabriel phthalimide synthesis
• C. Sandmeyer reaction
• D. Reaction with $N{H}_3$

Answer 1

The correct option is B Gabriel phthalimide synthesis

Best method for preparing primary aminos form alkyl halides without changing the number of carbon atoms in the chain is Gabriel synthesis. Because this process is used to get primary amine without changing number of carbon atom.
