Intermolecular Forces

Front

What are intermolecular forces?

Back

Forces that occur between molecules, affecting their physical properties.

Front

What is hydrogen bonding?

Back

A strong type of dipole-dipole attraction that occurs between molecules when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Front

Does HF have hydrogen bonding?

Back

Yes

Front

Does H2O have hydrogen bonding?

Back

Yes

Front

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

Back

Strong hydrogen bonds between water molecules.

Front

Which molecules can exhibit hydrogen bonding?

Back

Molecules where hydrogen is bonded to N, O, or F.

Front

Which of the following has hydrogen bonding: CBr4, NO2, H2S, NH3?

Back

NH3

Front

What is the main intermolecular force in water?

Back

Hydrogen bonding.

Front

What are dipole-dipole interactions?

Back

Attractions between polar molecules due to their positive and negative ends.

Front

What are dispersion forces?

Back

Weak intermolecular forces that arise from temporary shifts in electron density in atoms or molecules.
