IMF Practice

Front

What type of intermolecular force is primarily responsible for the high boiling point of water?

Back

Hydrogen Bonding is primarily responsible for the high boiling point of water due to the strong attractions between water molecules.

Front

In a structural formula, what does a single line (single bond) between two elements represent?

Back

A shared pair of electrons.

Front

What type of intermolecular force is most likely to occur between two nonpolar molecules?

Back

London Dispersion Forces are the primary intermolecular forces between nonpolar molecules.

Front

What is the weakest type of force found in all molecules, stronger in large molecules like I2?

Back

London Dispersion Forces are the weakest type of intermolecular force.

Front

Is this molecule polar or non-polar?

Back

Non-polar molecules have an even distribution of charge.

Front

Define Hydrogen Bonding.

Back

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

Front

What are London Dispersion Forces?

Back

London Dispersion Forces are weak intermolecular forces that arise from temporary dipoles in molecules, occurring in all molecules but are the only forces present in nonpolar molecules.

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

Front

What is a non-polar molecule?

Back

A non-polar molecule has an even distribution of electron density, resulting in no net dipole moment.

Front

Explain Dipole-Dipole Forces.

Back

Dipole-Dipole Forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.
