Questions and Answers

Why do haloalkanes tend to dissolve in organic solvents?

  • Haloalkanes form stronger hydrogen bonds with organic solvents
  • New intermolecular attractions between haloalkanes and solvent molecules have similar strength as the ones being broken (correct)
  • Haloalkanes have low polarity compared to organic solvents
  • Organic solvents have low density compared to haloalkanes
  • Why are haloalkanes very slightly soluble in water?

  • Haloalkanes have high polarity compared to water
  • Haloalkanes have low density compared to water
  • Haloalkanes form strong hydrogen bonds with water molecules
  • Energy is required to overcome attractions between haloalkane molecules and break hydrogen bonds in water (correct)
  • What happens to the energy when haloalkanes dissolve in water?

  • No energy change occurs during the dissolution of haloalkanes in water
  • Less energy is released when new attractions are set up between the haloalkane and the water molecules (correct)
  • More energy is released when haloalkanes dissolve in water
  • Energy is absorbed from the surroundings during dissolution
  • Why do haloalkanes have low solubility in water?
