Question
Describe the preparation of amines from haloalkanes. Include the type of reaction involved.
Answer
Amines can be prepared from haloalkanes through a nucleophilic substitution reaction with ammonia. In this reaction, the ammonia acts as a nucleophile, attacking the carbon atom bonded to the halogen, resulting in the displacement of the halogen and the formation of an amine.
Explanation
This answer is strong because it clearly identifies the reaction type (nucleophilic substitution) and the role of ammonia as a nucleophile. The question tests the student's understanding of amine preparation methods.
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.
