Web15 hours ago · CH2Cl2 Lewis Structure. The Lewis theory of chemical bonding—although quite primitive and the most limited theory on electronic structure—does help one to determine how valence electrons are arranged around the constituent atoms in a molecule. The purpose of this theory is to help visualize the chemical bonding of atoms in molecules. WebOct 27, 2006 · I'm trying to detect aqeous dichloromethane (methylene chloride) in GC-FID (Nucon 5670, India) using a capillary column (Permabond SE54HKW) with the folowing conditions, Inj: 220, Det: 240, oven: 120 degree C. with a split ratio of 1:25. For a concentration range of 25 to 1000 ppmv gas phase, the above conditions works well.
