  1. CH3Cl
  2. C2H5Cl
  3. C3H7Cl
  4. C4H9Cl

Questions & Step-by-Step Solutions

Which of the following haloalkanes has the highest boiling point?
  • Step 1: Understand that haloalkanes are compounds that contain carbon, hydrogen, and halogen atoms (like chlorine).
  • Step 2: Know that boiling point is affected by molecular weight and surface area.
  • Step 3: Compare the molecular weights of the given haloalkanes. Higher molecular weight usually means a higher boiling point.
  • Step 4: Consider the surface area of the molecules. Larger surface area can lead to stronger van der Waals forces, which also increases boiling point.
  • Step 5: Identify that C4H9Cl has a larger molecular weight and surface area compared to other haloalkanes.
  • Step 6: Conclude that C4H9Cl will have the highest boiling point among the options.
