How do you find the best Lewis structure?
Lewis structures are preferable when adjacent formal charges are zero or of the opposite sign. When we must choose among several Lewis structures with similar distributions of formal charges, the structure with the negative formal charges on the more electronegative atoms is preferable.
How do you find the Lewis symbol for an element?
Introduction. A Lewis Symbol is constructed by placing dots representing electrons in the outer energy around the symbol for the element. For many common elements, the number of dots corresponds to the element's group number. Below are Lewis Symbols for various elements.

What is the general formula for the homologous series to which propene belongs?
CnH2n Propene is an organic molecule that has an ending "ene", which means its belongs to the homologues series of alkenes. Table Q shows us the name, general formula, and examples of each homologues series. For alkenes, we see that the general formula is CnH2n. Therefore, the answer to this question is CnH2n.
