Mar 25, 2020 · Molecular shape is critical to the function of many biologically important molecules such as proteins. In addition, it can help explain differences in the attractive forces between molecules so it can help explain a host of physical properties including viscosity, surface tension and boiling point.
Recognize that molecule geometry is due to repulsions between electron groups. Recognize the difference between electron and molecular geometry. Name molecule and electron geometries for molecules with up to six electron groups surrounding a central atom. Compare bond angle predictions from the VSEPR-based model to real molecules.
1. CS2. (a) total valence electrons = carbon + 2*sulfur = 4 + 2*6 = 16. (b) the Lewis dot structure will have the carbon as the central atom. (c) Thus, the electronicshape is linear because there are two regions of electron density. (d) The molecular shape is also linear since there are no lone pairs on the central atom.
Worksheet 15 - Molecular Shapes The shapes of molecules can be predicted from their Lewis structures by using the VSEPR (Valence Shell Electron Pair Repulsion) model, which states that electron pairs around a central atoms will assume a geometry that keeps them as far apart from each other as possible. This is illustrated by the drawings below.
