The hybridization of the atoms in this idealized Lewis structure is given in the table below. For most types. Chloroethane, also called ethyl chloride, is a colorless gas at room temperature and pressure, with a characteristically sharp odor. As people say, Cl-S-Cl is polar because it is “bent” with a bond angle close to a right angle. A dot diagram (also called an Electron Dot Diagram, and a Lewis Structure) is a way to show the valence electrons that surround an element. Animal studies have given us an important opportunity to understand the mechanisms of action of many chemicals on the endocrine system and on neurodevelopment and behaviour, and to evaluate the effects of doses, time and duration of exposure.
