Question

1. choose the best answer.

which of these will form a compound with the highest boiling point?
metallic bonding
covalent bonding
ionic bonding
hydrogen

1. choose the best answer.

which form of matter has the strongest intermolecular force?
gas
liquid
solid
all of these

Explanation:

• For question 8: Ionic bonding generally forms compounds with high boiling points due to the strong electrostatic forces between ions. Metallic bonding also has high boiling points but ionic compounds often have higher. Covalent bonding (except for network covalent like diamond) has lower boiling points as they are usually molecular with weaker intermolecular forces. Hydrogen (as in hydrogen bonding, which is an intermolecular force, not a bonding type for compounds in the same sense as the others here) is weaker than ionic bonding.
• For question 9: Solids have the strongest intermolecular forces. In solids, the particles are closely packed and held together by strong forces, which gives them a definite shape and volume. Liquids have weaker intermolecular forces than solids (particles can move more freely) and gases have the weakest (particles are far apart and move freely).

Answer:

1. ionic bonding
2. solid
