Concept Introduction: The chemical compounds can be shown in different structural formulae. Condense formula, wedge-dashed formula and bond-line formula are some common ways to show the structural of chemical compounds.
In wedge-dashed line formula, the groups or atoms bonded to each C atoms must be shown with dashed and wedges. Here wedge is the solid line that represents the bond in plane of the surface whereas dash line represents the line extended back behind the surface.
In the bond line formula, each C is shown as dot and the each dot is connected with another dot with line. Excluding C and H, all other elements of the compound like N, S, O must be indicted with their atomic symbols. In Kekulè (straight line) notation all atoms and
