How do alkyl and aryl groups on nitrogen affect the basicity of an amine?
ABoth raise basicity
BAlkyl lowers, aryl raises
CAlkyl raises, aryl lowers
DNeither has any effect
Answer & Solution
Correct answer: C. Alkyl raises, aryl lowers
Alkyl groups push electron density onto nitrogen while aryl groups draw it away, so alkyl amines are stronger bases than aryl amines.
