• cohesion
• polar molecule
• hydrogen bond
• solution

Multiple Choice

Which type of bond is stronger – hydrogen or covalent?

• Covalent bond

• Hydrogen bond

• Both are equally strong

• Neither bond is strong

Multiple Select

Which is correct about this drawing? Choose 2 answers.

• A is pointing to a covalent bond

  B is pointing to a hydrogen bond

• A is pointing to a hydrogen bond
