Q: What is the effect of electron-withdrawing groups on the basicity of amines?
Solution: Electron-withdrawing groups decrease the basicity of amines by reducing the electron density on the nitrogen atom.
Steps: 6
Step 1: Understand what amines are. Amines are compounds that contain a nitrogen atom bonded to hydrogen atoms or carbon atoms.
Step 2: Know what basicity means. Basicity refers to the ability of a substance to accept protons (H+ ions).
Step 3: Learn about electron-withdrawing groups. These are groups of atoms that pull electrons away from other atoms, making them less electron-rich.
Step 4: Identify how electron-withdrawing groups affect nitrogen in amines. When these groups are attached to the amine, they reduce the amount of electron density on the nitrogen atom.
Step 5: Realize that less electron density on nitrogen means it is less able to attract protons. This makes the amine less basic.
Step 6: Conclude that the presence of electron-withdrawing groups decreases the basicity of amines.
