- A. Nucleophilic substitution of a primary amine with a halogenoalkane
- B. Reduction of nitro compounds
- C. Hydrolysis of nitriles
- D. Dehydration of primary amines
Answer
Nucleophilic substitution of a primary amine with a halogenoalkane
Explanation
Secondary amines can be prepared by the nucleophilic substitution of a primary amine with a halogenoalkane, resulting in the formation of a secondary amine.
Common mistake
Incorrect Reaction Conditions
Students often forget to specify the necessary reaction conditions for the preparation of amines, such as the use of a reducing agent or specific temperature.
Always include the required reaction conditions when describing the preparation of amines. For example, state that amines can be prepared by reducing nitro compounds using lithium aluminium hydride (LiAlH4) under anhydrous conditions.
