Intra/Inter Forces

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions). They play a crucial role in determining the physical properties of substances.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules. They are present in all molecules but are the only type of intermolecular force in nonpolar molecules.

Front

What are dipole-dipole forces?

Back

Dipole-dipole forces are intermolecular forces that occur between polar molecules, where the positive end of one molecule is attracted to the negative end of another.

Front

What is hydrogen bonding?

Back

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

Front

Which intermolecular force is the strongest?

Back

Hydrogen bonding is generally considered the strongest intermolecular force.

Front

Which intermolecular force is the weakest?

Back

London dispersion forces are the weakest intermolecular forces.

Front

How do intermolecular forces affect boiling points?

Back

Substances with stronger intermolecular forces have higher boiling points, while those with weaker forces have lower boiling points.

Front

What is the relationship between molecular size and London dispersion forces?

Back

As molecular size increases, London dispersion forces also increase due to a larger electron cloud, leading to stronger attractions.

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a positive and a negative end.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule is a molecule that does not have a net dipole moment, often due to symmetrical distribution of charge.
