Chemical Structure Description

A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The eugenol molecule contains a total of 24 bond(s). There are 12 non-H bond(s), 7 multiple bond(s), 3 rotatable bond(s), 1 double bond(s), 6 aromatic bond(s), 1 six-membered ring(s), 1 aromatic hydroxyl(s), and 1 ether(s) (aromatic). Images of the chemical structure of eugenol are given below:

3-dimensional (3D) chemical structure image of eugenol

The 2D chemical structure image of eugenol is also called skeletal formula, which is the standard notation for organic molecules. The carbon atoms in the chemical structure of eugenol are implied to be located at the corner(s) and hydrogen atoms attached to carbon atoms are not indicated – each carbon atom is considered to be associated with enough hydrogen atoms to provide the carbon atom with four bonds.

The 3D chemical structure image of eugenol is based on the ball-and-stick model which displays both the three-dimensional position of the atoms and the bonds between them. The radius of the spheres is therefore smaller than the rod lengths in order to provide a clearer view of the atoms and bonds throughout the chemical structure model of eugenol.
