As a language model AI, I cannot perform computational chemistry calculations directly. However, I can guide you through the process of finding the most stable conformation of 1,2-dichloroethane and analyzing its dipole moment using computational chemistry and molecular modeling.1,2-dichloroethane C2H4Cl2 has two conformations: the eclipsed or syn conformation and the staggered or anti conformation. To determine the most stable conformation and analyze the dipole moments, you can follow these steps:1. Choose a computational chemistry software: There are several computational chemistry software packages available, such as Gaussian, ORCA, or GAMESS. Choose one that you are familiar with or have access to.2. Build the molecule: Using the molecular editor in the chosen software, build the 1,2-dichloroethane molecule. You will need to create two conformations: eclipsed and staggered.3. Optimize the geometry: Perform a geometry optimization for both conformations using an appropriate level of theory, such as density functional theory DFT with the B3LYP functional and a suitable basis set like 6-31G d .4. Calculate the energy: After the geometry optimization, the software will provide the energy of each conformation. Compare the energies to determine which conformation is more stable. The lower energy conformation is the most stable one.5. Analyze the dipole moment: The software should also provide the dipole moment for each optimized conformation. Compare the dipole moments to understand how the conformation affects the molecule's dipole moment.In general, the staggered anti conformation of 1,2-dichloroethane is more stable than the eclipsed syn conformation due to reduced steric strain between the chlorine atoms. The dipole moment of the anti conformation is typically lower than that of the syn conformation because the two C-Cl bond dipoles are oriented in opposite directions, partially canceling each other out.
