complete a Carvone Lewis structure that displays all valence electrons, all atoms and all the formal charges, if any. Use only a single dash for each pair of bonding electrons and a pair of dots for all nonbonding pairs of electrons. Identify and label all functional groups (alcohols, amines, amides, carboxylic acids, ketones, aldehydes, aromatic rings, aromatic amines, etc) on the Lewis Structure. You do not have to circle alkanes. (Must be included in the preliminary submission and in the PowerPoint.)

For each of tthe following structural formulas, provide the indicated number of resonance structures. Use curved arrows to show the electron movement between each structure, use double headed arrow to separate the structures, and enclose all of them in a single set of brackets
This is done by removing an unshared pair from each of two adjacent atoms and adding one electron pair as a second bond between the atoms. Each such operation reduces the number of electrons in the trial structure by two. Removing the unshared pairs of electrons on the carbon atoms and adding a second carbon–carbon bond gives a structure in which there are four electrons involved in a double bond between the carbon atoms. The trial structure now contains electrons ____ and is correct.
