Organic Chemistry Ways to Draw and Represent Molecules Skeletal Structure. 1 Answer Trevor Ryan. Dots and Lines are used in this structure in which lines represent the electrons forming bonds with the central atom and dots are the non-bonding pairs. Now, try this - instead of memorizing each structure, cover the structural formula and try to deduce it from the name of the isomer alone. (d) Only one pair of enantiomers is possible for 2,2 -dichlorobicyclo[2.2.1]heptane. Lewis structure is the structural representation of the number of valence electrons that participate in the bond formation and nonbonding electron pairs.
