Cheat Sheet
- Hydrogen Bonding in CH₃OH -
Methanol exhibits strong hydrogen bonding due to the O - H group, which raises its boiling point significantly above similarly sized molecules (Chemguide, University of Cambridge). These interactions are the primary intermolecular forces in CH₃OH, making it more cohesive and giving it a higher heat of vaporization.
- Polarity and Hydrogen Fluoride IMFs -
HF is a highly polar molecule because of the large electronegativity difference between H and F, so it forms both strong hydrogen bonds and dipole - dipole interactions (American Chemical Society). This combination explains HF's anomalously high boiling point compared to other hydrogen halides.
- Does HF Have Dipole - Dipole Forces? -
Yes - in addition to hydrogen bonding, HF has classic dipole - dipole attractions as the H - F bond generates a permanent dipole moment (IUPAC Gold Book). These forces work alongside hydrogen bonds to stabilize liquid HF and contribute to its unique physical properties.
- Intermolecular Force of CF₄ -
Carbon tetrafluoride is nonpolar and lacks any dipole or hydrogen bonds, so its only intermolecular attractions are London dispersion forces (Journal of Chemical Education). These weak, temporary dipoles explain CF₄'s low boiling and melting points despite its tetrahedral symmetry.
- Comparing IMF Strengths: CH₃OH, HF, and CF₄ -
Ranked by strength: HF (strongest due to hydrogen bonding + dipole - dipole) > CH₃OH (hydrogen bonding) > CF₄ (dispersion only). Remember the mnemonic "HDL" (Hydrogen & Dipole > Liquid dispersion) to recall why HF outweighs methanol, with CF₄ trailing.
