Are secondary amines more basic than primary?
In general, secondary amines are more basic than primary amines, which are more basic than tertiary amines. Amines are capable of forming hydrogen bonds with water and therefore have strong intermolecular forces that result in higher melting points, boiling points, and water solubility.
Is primary or secondary amine more reactive?
The secondary amines are more reactive than primary amines of similar basicity for the S-O bond fission. The k(1) value has been determined to be larger for reactions with secondary amines than with primary amines of similar basicity, which fully accounts for their higher reactivity.
