Representations of Structural Formulas There are a number of ways to write structural formulas. Each conveys some idea or information about the structure. Dot Structures (Lewis Structures) These structures emphasize the number of valence electrons . They help in recognizing a correct valence bond structure in conjunction with the octet rule. But using dots for covalent bonds is tedious, and they are rarely used. Dash or Line Formulas These structural formulas where each pair of electrons in a covalent bond is represented as a line are widely used. When the nonbonding electron pairs are shown as dots, these formulas provide an accounting of all the valence electrons. Sometimes the nonbonding electrons are omitted.

Condensed Formulas In these widely used structural formulas, the bonding is implied by the order in which the atoms appear. The sequence of central atoms is written from left to right. The hydrogens and other atoms that are bonded to a central atom appear immediately after that
