• A. Van der Waals interaction
• B. Ionic bond
• C. Covalent bond
• D. Hydrogen bond

Answer: (C)

Verified step by step guidance

1. Understand the different types of chemical bonds and interactions: Van der Waals interactions, ionic bonds, hydrogen bonds, and covalent bonds.
2. Recall that Van der Waals interactions are weak forces caused by temporary dipoles and are generally the weakest among these options.
3. Recognize that ionic bonds are formed by the electrostatic attraction between oppositely charged ions and are relatively strong but can be disrupted in polar solvents like water.
4. Know that hydrogen bonds are a type of dipole-dipole interaction involving hydrogen atoms bonded to electronegative atoms; they are stronger than Van der Waals but weaker than ionic and covalent bonds.
5. Identify that covalent bonds involve the sharing of electron pairs between atoms, creating a strong and stable bond that is typically the strongest and most secure among the options, making it critical where strength and stability are required.
