SCC 202 Gaussian Lab Experiment - Dipole Moments with Sample Results Integrative Learning and Digital Communication Ability ___________________________________________________ Learning objectives1. Use Gaussian modeling software to determine the dipole moment of molecules 2. Relate molecular polarity to the intermolecular forces of the molecule. 3. Which types of compounds have the strongest intermolecular forces? 4. Relate intermolecular forces of the molecule to physical properties such as boiling point
(1) Dipole moment shows polarity of the compound.
Dipole moment = 4× length
(2) Higher the inter molecular force than higher the polarity.
(3) Inter molecular force in increasing order is hydrogen bonding, induced Dipole interaction, Dipole, distortion.
(4) Boiling point is directly proportional to intermolecular force.
