Questions & Step-by-Step Solutions

What is the effect of increasing the number of alkyl groups on the basicity of amines?
  • Step 1: Understand what amines are. Amines are compounds that contain nitrogen atoms bonded to carbon atoms.
  • Step 2: Know that basicity refers to the ability of a substance to accept protons (H+ ions).
  • Step 3: Recognize that alkyl groups are carbon chains that can be attached to the nitrogen in amines.
  • Step 4: Learn that alkyl groups are electron-donating, meaning they can push electrons towards the nitrogen atom.
  • Step 5: Realize that when more alkyl groups are added to an amine, the nitrogen atom becomes more electron-rich.
  • Step 6: Understand that a more electron-rich nitrogen can better attract and hold onto protons, making the amine more basic.
  • Step 7: Conclude that increasing the number of alkyl groups generally increases the basicity of amines.
