Intermolecular Forces Reading Quizizz Lesson

Which of the following describes what happens when water is boiled?

• Forces of attraction between water molecules are made weaker and water molecules can move farther apart from each other and water vapor is formed

• Covalent bonds between hydrogen and oxygen are made weaker and hydrogen gas and oxygen gas are formed.

• Forces of attraction between water molecules grow stronger and water molecules can move farther apart from each other and water vapor is formed

• Covalent bonds between hydrogen and oxygen are made stronger and water vapor forms.

Select all the lines that indicate intermolecular forces in a sample of water molecules

Intermolecular forces are ​​ (a)   than covalent and ionic bonds

• stronger
• equally as strong as

Select the description of a dipole and the picture that represents a bond with a dipole.

• A dipole is an uneven distribution of electrons between atoms caused from differences in electronegativities

• A dipole is an even distribution of electrons between atoms caused from similarities in electronegativities
