Q: What kind of bonding between alcohol molecules means that more energy is required to convert the liquid to vapor, and boiling points are therefore high?


Read this paragraph and choose the correct option from the provided answers:

Only weak London dispersion forces hold molecules of nonpolar alkanes together in the liquid phase. Consequently, less energy is required to break these molecules away from the surface of the liquid and turn them into a vapor. The stronger hydrogen bonding between alcohol molecules means that more energy is required to convert the liquid to vapor, and boiling points are therefore high.

 Choices:

- weaker carbon bonding

- stronger mineral bonding

- stronger diffusion bonding

- stronger hydrogen bonding


A:
stronger hydrogen bonding
