Learn to determine if CH3COOH (Acetic acid) is polar or non-polar based on the Lewis Structure and the molecular geometry (shape). • We start with the Lewis Structure and look and the polarity of the individual bonds in Acetic acid based on the electronegativity difference between atoms. Then we will use VSEPR to determine the shape of the molecule and look at how the shape of the molecule allows us to determine if the entire molecule is polar or nonpolar. • Lewis Structure for CH3COOH: • Video • If you look at the Lewis structure for CH3COOH it does not appear a symmetrical molecule. However, to determine if CH3COOH is polar we must consider the molecular geometry. A polar molecule results from an unequal/unsymmetrical sharing of valence electrons. In CH3COOH the sharing is not equal and there is a net dipole. Therefore, CH3COOH is a polar molecule. • Get more chemistry help at http://www.breslyn.org . • More Learning Resources • • Polar and Non-Polar Tutorial: • Polar, Non-Polar, and Ionic Compounds... • • Drawing Lewis Structures: • Lewis Structures for Covalent Molecul... • • Determining Molecular Geometry: • Molecular Geometry: Rules, Examples, ... • • Periodic Table with Electronegativity Values: https://en.wikipedia.org/wiki/Electro...) • • Molecular Geometry App Used in Video: https://phet.colorado.edu/sims/html/m... • Electrostatic map of CH3COOH from: • http://www.chem.ucalgary.ca/courses/3... • Get more chemistry held at www.Breslyn.org . • Drawing/writing done in InkScape (www.InkScape.org).
