Ngac (ttn793) h11: solids and liquids mccord (51600) Multiple-choice questions may continue on the next column or page nd all choices before answering: none of these, armed forces. What would be the most signi cant type of intermolecular forces in a liquid sample of. Uoroform (chf3): ionic, hydrogen bonding, dispersion, dipole-dipole correct, covalent. Waals or induced dipoles all describe the same intermolecular force. London forces are in- duced, short-lived, and very weak. Molecules and atoms can experience london forces be- cause they have electron clouds. London forces result from the distortion of the elec- tron cloud of an atom or molecule by the presence of nearby atoms or molecules. Permanent dipole-dipole interactions are stronger than london forces and occur be- tween polar covalent molecules due to charge separation. Ion-ion interactions are the strongest due to extreme charge separation and occur between ionic molecules. They can be thought of as both inter- and intramolecular bonding.
