Lesson 970 of 1524
Amines and Heterocycles
The chemistry of amines is dominated by the lone-pair electrons on nitrogen, which makes amines both basic and nucleophilic.
Practice this chapterThe chemistry of amines is dominated by the lone-pair electrons on nitrogen, which makes amines both basic and nucleophilic. The basicity of arylamines is generally lower than that of alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic π system.
We’ve now seen all the common functional groups that occur in organic and biological chemistry. Of those groups, amines are among the most abundant and have among the richest chemistry.
basicity of arylamines — generally lower than that of alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic π system. chemistry of amines — dominated by the lone-pair electrons on nitrogen, which makes amines both basic and nucleophilic.
Worked example
What does “basicity of arylamines” mean in Amines and Heterocycles?
- 1Use the wording this chapter gives for basicity of arylamines.
- 2The book says: generally lower than that of alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic π system.
- 3Do not use the meaning of chemistry of amines. That term means dominated by the lone-pair electrons on nitrogen, which makes amines both basic and nucleophilic.
Result: generally lower than that of alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic π system
Why. That is the meaning this chapter gives for basicity of arylamines.
Do not swap basicity of arylamines and chemistry of amines. basicity of arylamines means generally lower than that of alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic π system. chemistry of amines means dominated by the lone-pair electrons on nitrogen, which makes amines both basic and nucleophilic.
