Question
- A. Alkyl groups decrease basicity
- B. Alkyl groups increase basicity
- C. Alkyl groups have no effect
- D. Alkyl groups make amines neutral
Answer
Alkyl groups increase basicity
Explanation
Alkyl groups increase the electron density on the nitrogen atom due to inductive effects, enhancing the basicity of amines compared to ammonia.
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.
