Polarity and Intermolecular Forces Review

Front

What happens to the boiling point of a substance when its intermolecular forces are weaker?

Back

The boiling point is lower.

Front

Which substance has the weakest intermolecular forces of attraction?

Back

CH₄ (Methane)

Front

What properties are affected by intermolecular forces (IMFs)?

Back

Boiling Point, Melting Point, Surface Tension - all are affected by IMFs.

Front

What is required for hydrogen bonding to occur?

Back

A hydrogen atom must be bonded to Fluorine, Nitrogen, or Oxygen.

Front

What are the forces that hold atoms together within a molecule called?

Back

Intramolecular forces.

Front

Define intermolecular forces.

Back

Forces that occur between molecules, affecting physical properties like boiling and melting points.

Front

What is the relationship between intermolecular forces and boiling point?

Back

Stronger intermolecular forces result in a higher boiling point.

Front

Give an example of a substance with strong hydrogen bonding.

Back

Water (H₂O) is an example of a substance with strong hydrogen bonding.

Front

What type of intermolecular force is present in NaCl?

Back

Ionic bonds, which are stronger than typical intermolecular forces.

Front

How do intermolecular forces affect surface tension?

Back

Stronger intermolecular forces lead to higher surface tension.
