dōTERRA is of Latin origin and means
"Gift of the Earth."
An important skill in chemistry is the ability to draw and recognize the structures of different molecules. Generally, molecules are drawn using the symbols of the atoms (remember the symbol can be found on the Periodic Table) that are connected with straight lines. These lines represent the covalent chemical bonds that are formed between the atoms making up a molecule. One line indicates a single bond, two lines indicate a double bond, and three lines indicate a triple bond. Below is a chart showing the name and chemical structure for some simple molecules. In the chemical structures below, note the atoms themselves and the bonds between them.
Because hydrocarbons occur so frequently in organic chemistry, there is a simplified way for drawing their structures. With this simplified method, carbons are represented by corners or the end of a line and the lines themselves represent chemical bonds. Hydrogen atoms are omitted from the depictions and their position is assumed in any space not filled with a bond to another molecule (remember that each carbon will always have a total of four bonds). Any atoms other than carbon and hydrogen are depicted with their proper chemical symbol. Look at the chart of molecules below. In the first column is the molecule’s name, in the second column is the molecule’s structure in shorthand notation.
