Forces and Bonding Quiz

Define intermolecular forces.

• Forces within a molecule that hold atoms together

• Forces between molecules that affect their physical properties

• Forces that only exist in ionic compounds

• Forces that are responsible for nuclear reactions

DOK Level 1: Recall

Which of the following substances is likely to have the highest boiling point?

• Methane (CH₄)

• Water (H₂O)

• Oxygen (O₂)

• Nitrogen (N₂)

DOK Level 2: Skill/Concept

Explain why fluorine has a higher electronegativity than iodine.

• Fluorine has more protons than iodine.

• Fluorine is smaller in size, allowing it to attract electrons more effectively.

• Iodine has a higher atomic mass, reducing its electronegativity.

• Fluorine is a noble gas, which increases its electronegativity.
