  4. Dimethylamine

Questions & Step-by-Step Solutions

Which of the following amines has the highest boiling point?
  • Step 1: Understand what amines are. Amines are organic compounds that contain nitrogen atoms.
  • Step 2: Know that boiling point is affected by the strength of intermolecular forces.
  • Step 3: Identify the types of intermolecular forces present in amines, such as hydrogen bonding.
  • Step 4: Recognize that hydrogen bonds are stronger than other types of intermolecular forces like van der Waals forces.
  • Step 5: Compare the amines given in the question. Look for the one that can form the most hydrogen bonds.
  • Step 6: Determine that aniline, which has an -NH2 group, can form strong hydrogen bonds due to its structure.
  • Step 7: Conclude that aniline has the highest boiling point among the options because of its strong hydrogen bonding capability.
