Honors Intermolecular Forces

Front

What type of intermolecular force is present in ammonia (NH₃)?

Back

Hydrogen bonding.

Front

In a polar covalent bond, where do the electrons tend to gather?

Back

Mostly around the atom with the greatest electronegativity.

Front

What type of intermolecular force is present in Cl₂?

Back

Dispersion forces.

Front

What are intermolecular forces?

Back

Forces that occur between molecules.

Front

What type of intermolecular force is responsible for dipole-dipole attraction?

Back

Dipole-dipole attraction occurs between polar molecules.

Front

Define London Dispersion Forces.

Back

Weak intermolecular forces arising from temporary dipoles in molecules.

Front

What is the significance of hydrogen bonding in water?

Back

Hydrogen bonding gives water its unique properties, such as high boiling point and surface tension.

Front

How do dipole-dipole forces differ from hydrogen bonds?

Back

Dipole-dipole forces occur between polar molecules, while hydrogen bonds are a stronger type of dipole-dipole interaction involving H bonded to N, O, or F.

Front

What is the relationship between electronegativity and polarity in covalent bonds?

Back

Greater differences in electronegativity between atoms lead to more polar covalent bonds.

Front

What is the primary intermolecular force in nonpolar molecules?

Back

London Dispersion Forces.
