Intermolecular 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.

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of chemical bond where two atoms share a pair of electrons with each other equally, resulting in no charge separation.

Front

In a nonpolar covalent bond, how do electrons distribute themselves?

Back

Electrons gather around each atom equally.

Front

What is 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 nitrogen, oxygen, or fluorine.

Front

Does HF exhibit hydrogen bonding?

Back

Yes, HF exhibits hydrogen bonding due to the presence of hydrogen bonded to fluorine.

Front

What type of intermolecular force is present in HCl?

Back

HCl exhibits dipole-dipole intermolecular forces.

Front

What explains the high melting and boiling points of water?

Back

The very high melting and boiling points of water are explained by the strong hydrogen bonds between water molecules.

Front

How do intermolecular forces affect boiling points?

Back

The weaker the intermolecular forces of a substance, the lower the boiling point.

Front

What are dispersion forces?

Back

Dispersion forces, also known as London dispersion forces, are weak intermolecular forces that arise from temporary shifts in electron density in atoms or molecules.

Front

What is the relationship between electronegativity and bond polarity?

Back

The greater the difference in electronegativity between two bonded atoms, the more polar the bond will be.
