Challenge Problems

Push your limits with challenges.

Question 1

Describe a situation where you would compare the boiling points of two substances, one with strong hydrogen bonds and another with only London dispersion forces. What factors would you consider?

💡 Hint: Think about why we need heat to change states.

Question 2

A liquid has a lower viscosity than another; deduce which intermolecular forces might be weaker in the less viscous liquid and explain.

💡 Hint: Consider how viscosity relates to the movement of molecules.
