Properties of Covalent Compounds Quiz

What is the primary learning goal for the lesson on covalent compounds?

• To understand ionic bonds

• To describe the properties of covalent compounds

• To learn about metallic bonds

• To study intermolecular forces

How do non-polar covalent compounds form?

• By sharing electrons unequally

• By sharing electrons equally

• By forming ions

• By transferring electrons

What causes polar covalent compounds to have a slight charge?

• Formation of ions

• Equal sharing of electrons

• Transfer of electrons

• Unequal sharing of electrons

Which state of matter are non-polar covalent compounds most likely to be at room temperature?

• Solid

• Liquid

• Gas

• Plasma

Why do polar covalent compounds have higher melting points than non-polar ones?

• Due to slight positive and negative charges

• Because they form ions

• Because of equal electron sharing

• Due to strong ionic bonds

Why are covalent compounds generally poor conductors of electricity?

• They do not form ions

• They dissolve well in water

• They form ions easily

• They have high melting points

In which type of liquid are covalent compounds more soluble?

• Non-polar liquids

• Polar liquids

• Ionic liquids

• Metallic liquids

What happens when non-polar covalent compounds are mixed with water?

• They conduct electricity

• They dissolve completely

• They form ions

• They clump together and separate from water

Which of the following is a characteristic of polar covalent compounds?

• They have slight positive and negative charges

• They have high boiling points

• They are good conductors of electricity

• They dissolve well in non-polar solvents

What is the main reason covalent compounds have low boiling points?

• Strong ionic bonds

• Formation of ions

• Weak intermolecular forces

• High solubility in water
