A step-by-step explanation of how to draw the C6H6 Lewis Dot Structure (Benzene).

There are several ways to draw the C6H6 Lewis structure.  The most common is to form a ring with the six carbon atoms.  You'll notice that there are not many hydrogen atoms in the structure.   You'll need to form alternating double bonds in order to fill the outer shells of the atoms and only use 30 valence electrons.

There are two other (probably more than that) ways to draw the Lewis structure for C6H6.  These are equally valid structures and obey the octet rule while using only 30 valence electrons.

For the C6H6 structure use the periodic table to find the total number of valence electrons for the C6H6 molecule. Once we know how many valence electrons there are in C6H6 we can distribute them around the central atom with the goal of filling the outer shells of each atom.

In the Lewis structure of C6H6 structure there are a total of 30 valence electrons. C6H6 is also called Benzene.

---- Steps to Write Lewis Structure for compounds like C6H6 ----
1. Find the total valence electrons for the C6H6 molecule.
2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside.
3. Put two electrons between atoms to form a chemical bond.
4. Complete octets on outside atoms.
5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds.

Lewis Structures, also called Electron Dot Structures, are important to learn because they help us understand how atoms and electrons are arranged in a molecule, such as Benzene. This can help us determine the molecular geometry, how the molecule might react with other molecules, and some of the physical properties of the molecule (like boiling point and surface tension).
