Front

What explains the very high melting and boiling point of water?

Back

Strong hydrogen bonds between water molecules.

Front

Which substance has the weakest intermolecular forces of attraction: CH4 or H2O?

CH4 has the weakest intermolecular forces.

Front

Define intermolecular forces.

Back

Forces that occur between molecules, affecting their physical properties.

Front

What are the three main types of intermolecular forces?

Back

Dipole-dipole interactions, hydrogen bonding, and London dispersion forces.

Front

How do hydrogen bonds compare to other types of intermolecular forces?

Back

Hydrogen bonds are stronger than dipole-dipole interactions and London dispersion forces.

Front

What is the significance of dipole-dipole interactions?

Back

They occur between polar molecules and influence boiling and melting points.

Front

What are London dispersion forces?

Back

Weak intermolecular forces arising from temporary dipoles in molecules.
