Can hydrogen bonding account for viscosity?
Neither ethanol nor methanol, the alcohols in which hydrogen bonding most strongly operates, are particularly viscous (the same for water). Therefore, viscosity cannot solely be attributed to hydrogen bonding.
Conversely, as the chain length increases, so does the possibility of chain/chain interaction, which raises boiling points. In long chain alcohols, the polar heads would then aggregate, strengthening the chain/chain interaction (cf. detergents). As a result, both alcohols and alkanes tend to become more viscous and syrupy. This intermolecular force can be attributed to dispersion forces.

Yes, hydrogen bonding can contribute to viscosity in liquids. Hydrogen bonding between water molecules, for example, creates cohesive forces that make it more resistant to flow, resulting in higher viscosity.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How do you find vapor pressure?
- Octane has a molar mass of 114 grams per mole. What is the boiling point of octane at standard pressure?
- Compared to most other substances, a great deal of heat is needed to raise the temperature of by a given amount. What trait of water allows this to take place?
- True or false: at the boiling point, the vapour pressure of the liquid is always ONE atmosphere?
- Are the best conductors are usually solids, liquids, or gases?
