Highest boiling point between organic compounds

Click For Summary
SUMMARY

The discussion centers on determining which organic compound has the highest boiling point among substances with similar relative molecular masses. The consensus is that compound E, which contains an -OH group, exhibits hydrogen bonding, leading to a higher boiling point. Participants confirm the importance of consulting boiling point data for verification, emphasizing the role of intermolecular forces in boiling point determination.

PREREQUISITES
  • Understanding of intermolecular forces, specifically hydrogen bonding
  • Familiarity with organic compound structures and functional groups
  • Knowledge of boiling point concepts and measurement
  • Ability to reference and interpret chemical data tables
NEXT STEPS
  • Research the impact of hydrogen bonding on boiling points in organic compounds
  • Learn how to use chemical data tables to find boiling points of various substances
  • Explore the relationship between molecular structure and boiling point
  • Investigate other types of intermolecular forces, such as dipole-dipole interactions and London dispersion forces
USEFUL FOR

Chemistry students, organic chemists, and anyone studying the physical properties of organic compounds will benefit from this discussion.

The Attempt at a Solution


I chose E as it has OH so therefore hydrogen bonding. Is this correct?

Cheers!
