Q: What is to blame for water’s boiling point (100°c) being higher than the boiling points of similar substances?


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

Hydrogen bonds also explain why water’s boiling point (100°C) is higher than the boiling points of similar substances without hydrogen bonds. Because of water’s relatively high boiling point, most water exists in a liquid state on Earth. Liquid water is needed by all living organisms. Therefore, the availability of liquid water enables life to survive over much of the planet.

 Choices:

- electrode bonds

- molecular shape

- helium bonds

- hydrogen bonds


A:
hydrogen bonds
