Writing Lewis Formulas: Limitations of the Octet Rule Example 7-6: Write dot and dash formulas for AsF 5 . You do it! Resonance There are three possible structures for SO 3 . The double bond can be placed in one of three places. Resonance Resonance is a flawed method of representing molecules. There are no single or double bonds in SO 3 . In fact, all of the bonds in SO

Unformatted text preview: 3 are equivalent. The best Lewis formula of SO 3 that can be drawn is: Polar and Nonpolar Covalent Bonds Covalent bonds in which the electrons are shared equally are designated as nonpolar covalent bonds. Nonpolar covalent bonds have a symmetrical charge distribution. To be nonpolar the two atoms involved in the bond must be the same element to share equally. Polar and Nonpolar Covalent Bonds Some examples of nonpolar covalent bonds. H 2 N 2 Polar and Nonpolar Covalent Bonds...
