- A. Nucleophilic substitution with ammonia
- B. Electrophilic addition with water
- C. Reduction of nitro compounds
- D. Dehydration of alcohols
Answer
Nucleophilic substitution with ammonia
Explanation
Amines can be prepared from halogenoalkanes through nucleophilic substitution, where ammonia acts as a nucleophile, replacing the halogen atom.
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.
