Final answer:
Electrostatic forces have the longest range of interaction in an aqueous solution of 0.1 M NaCl, dominating over ion-dipole, hydrogen bonding, and Van der Waals forces due to the presence of charged ions that affect other charged particles over large distances.
Step-by-step explanation:
Among the forces listed in the question, electrostatic forces have the longest range of interaction in an aqueous solution of 0.1 M NaCl. Electrostatic forces are interactions between charged particles, and in the context of an ionic solution, they represent the ion-ion interactions that are responsible for ionic bonding, as well as the ion-dipole interactions that occur when ionic substances dissolve in water.
NaCl is an ionic compound that dissociates in water to form Na+ and Cl- ions. These ions create an electric field around them due to their charge, and this field can influence other charged particles over relatively large distances compared to other intermolecular forces. Therefore, the electrostatic force represented by the ion-ion interaction is the dominant long-range force within the 0.1 M NaCl aqueous solution.
