Both intra- and intermolecular forces are considered what kind of attraction?

• A. Gravitational attraction
• B. Magnetic attraction
• C. Nuclear attraction
• D. Electrostatic attraction

Answer: (D)

Verified step by step guidance

1. Understand that both intramolecular and intermolecular forces involve interactions between charged particles or regions of molecules.
2. Recall that intramolecular forces are the forces holding atoms together within a molecule, such as covalent or ionic bonds, which arise from attractions between positively charged nuclei and negatively charged electrons.
3. Recognize that intermolecular forces are attractions between molecules, such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces, which also depend on the attraction between partial or full charges.
4. Identify that these forces are fundamentally due to the attraction between positive and negative charges, which is described by electrostatic forces.
5. Conclude that both intra- and intermolecular forces are types of electrostatic attraction, as they arise from the interactions between charged particles or regions.
