Two or more elements that are held together by a chemical bond results in a compound. For instance, the combination of the elements sodium and chlorine results in the formation of sodium chloride (table salt). Thus, a substance comprised of only one type of element is not a chemical compound but an allotrope of an element.
Compounds and Molecules. A compound is a unique substance that consists of two or more elements combined in fixed proportions. This means that the composition of a compound is always the same. The smallest particle of most compounds in living things is called a molecule. Consider water as an example.

Mixtures are composed of variable proportions of molecules and atoms. The composition of a mixture is variable with each components retaining its characteristic properties. Its components are easily separated. Examples of Mixtures: soil, ocean water and other solutions, air, the cytosol of a cell.
A molecule is a group of two or more atoms bonded together, while a compound is a type of molecule that contains different elements.
Organic Compound Definition. An organic compound is a compound that, in general, contains carbon covalently bound to other atoms, especially Carbon-Carbon (C-C) and Carbon-Hydrogen (C-H) (such as in hydrocarbons). A chemical compound refers to any substance made up of two or more elements that are chemically bonded together.
