Document Summary
Chemical formulae: a chemical formula describes the combination of any substance. It shows the relative number of each type of atom in a substance. This is due to the covalent inorganic compounds which are small molecules that exist as rings and chains. Isomers are molecules that have the same chemical formula but different chemical structures. Ball-and-stick models: the balls represent atoms, the sticks represent the bonds. Space-filling models: the distorted sphere represents the volume occupied by its electrons, the spheres joins together to build a molecule. Functional groups: a group of one or more atoms within a molecule that is bonded together in a particular way. Carboxylic acids: carboxyl acid (-cooh, always found at the end of a carbon chain. The nomenclature of alkanes: alkanes are molecules that contain carbon and hydrogen where carbon are joined by single bonds. Constitutional isomerism in alkanes: compounds with the same chemical formula but a different order of attachment of the constitute atoms.
