Intermolecular Forces Worksheet 2 Answers 1 Using your hundred of molecular structure identify the main intermolecular force in fear following compounds. Because gaseous molecules are so far apart from one another, intermolecular forces are nearly nonexistent in the gas state, and so the dispersion forces in chlorine and fluorine only become measurable as the temperature decreases and they condense into the liquid state. Please show your work but via typing it NOT WRITING IT IN YOUR. Introduction: Ionic bonds, like those found in NaCl, form crystalline solids. Intermolecular forces AP.Chem: SAP5 (EU), SAP5.A (LO), SAP5.A.1 (EK), SAP5.A.2 (EK), SAP5.A.3 (EK), SAP5.A.4 (EK) Google Classroom In the vapor phase, formic acid exists as dimers (complexes consisting of two formic acid molecules) rather than individual molecules. An intermolecular force is a physical interaction between two separate molecules. In this case, even though it contains polar bonds, the molecule as a whole may be nonpolar.C.
