Res. ; van der Velde, L.E. Lewis Structure: The first step towards writing the Lewis structure of a molecule is to arrange the constituent atoms according to the structure of the molecule. Single lines are single bonds, double lines are double bonds, and triple lines are triple bonds. The Lewis structure depicts the arrangement of valence electrons among atoms in a molecule. With respect to chemical bonding, which particles play the least active role? Korean Chem. a. CH2O b. C2Cl4 ; Brinkman, U.A.Th.
