STRUCTURE & BONDING Introduction The physical properties (boiling point, conductivity, strength) of a substance depend on its structure and type of bonding. Bonding determines the structure.
The shape of a molecule can be determined by considering the type and quantity of electron pairs: Find the number of electron pairs. Determine how many of the pairs are bonding pairs and how many are lone pairs. Bonding pairs indicate the basic shape and lone pairs indicate any additional repulsion.

A bromide ion is the negatively charged form (Br−) of the element bromine, a member of the halogens group on the periodic table. Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3] .
To review the basics concepts of atomic structure that have direct relevance to the fundamental concepts of organic chemistry. This material is essential to the understanding of organic molecular structure and, later on, reaction mechanisms.

A simpler alternative is the Lewis structure, in which a single covalent bond is depicted by a single line connecting two atoms. Each line represents two electrons that are being shared between the connected atoms (Figure 9).

Because organic chemistry can involve large molecules it would be beneficial if Lewis structures could be abbreviated. The three different ways to draw organic molecules include Kekulé Formulas, Condensed Formulas, and Skeletal structures (also called line-bond structures or line formulas).
