5 Questions
Why do the boiling points and melting points rise as the number of carbons increases?
Because the intermolecular forces increase as the molecules get larger
What is required to occur during the processes of boiling and melting?
Overcoming the intermolecular forces of a liquid and a solid
What happens to the intermolecular forces as the molecules get larger?
They increase
What is the relationship between the number of carbons and the boiling points and melting points?
The boiling points and melting points rise as the number of carbons increases
What is the result of overcoming the intermolecular forces during boiling and melting?
The change from one state of matter to another
Study Notes
Trends in Boiling and Melting Points
- As the number of carbons in a molecule increases, its boiling point and melting point also increase.
- This trend is due to the strengthening of intermolecular forces between molecules as they get larger.
- Boiling and melting require overcoming these intermolecular forces in a liquid and a solid, respectively.
This quiz covers the relationship between the number of carbons in a molecule and its boiling and melting points, including the role of intermolecular forces.
