Why do amines act as nucleophiles?

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Definition of Nucleophiles**: - Nucleophiles are species that have a tendency to donate an electron pair to form a chemical bond. They are often negatively charged or have lone pairs of electrons that can be shared. 2. **Lone Pair of Electrons in Amines**: - Amines contain a nitrogen atom that has a lone pair of electrons. This lone pair is crucial for the nucleophilic behavior of amines. The general structure of amines can be represented as R-NH2 (for primary amines), where R is an alkyl or aryl group. ...
