Find the suitable method from the following to prepare primary amines without the loss of carbons.
- A Gabriel method
- B Alkylation method
- C Hoffmann bromamide method
- D Stephen method
Answer & Solution
Correct Answer
(A) Gabriel method
Step-by-step Solution
Detailed explanation
Gabriel phthalimide synthesis is used for the preparation of aliphatic primary amines without the loss of carbons. It involves nucleophilic substitution (SN2) of alkyl halides by the anion formed by the phthalimide. Phthalimide on treatment with ethanolic KOH forms potassium…
