Lewis structures, also known as electron dot structures, are named after Gilbert N. Lewis, who described them in a 1916 article titled, "The Atom and the Molecule." Lewis structures depict the bonds between atoms of a molecule, as well as any unbonded electron pairs. Weve already completed the first step, i.e., to calculate the number of valence electrons available. According to VSEPR theory, the electrons create a negatively charged atmosphere around the atomic nuclei and this creates a repulsive force among the like charges. 2.1 Computed Descriptors2.1.1 IUPAC Name Help New Window.

Therefore, the final Lewis structure for acetone [C, The molecular shape of the acetone molecule is trigonal planar due to it having an AX, Lets quickly summarize the salient features of C. O consists of three carbon atoms, six hydrogen atoms, and a lone oxygen atom. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Oxygen has six valence electrons in its outer shell and needs two electrons to follow the octet rule; hence its valency is 6. You might have heard chemistry is full of exceptions and one such exception is that Hydrogen tends to achieve Helium configuration hence will need a total of 2 electrons to fulfill the valence shell. Being in group 6 of the periodic table, oxygen has six valence electrons and has a valency of -2. Draw the lewis structure .
