CARBON TO CARBON BONDING
- We know from the periodic table Carbon atoms have 4 valence electrons on the outer shells.
- According to the Octet Rule of Electron Configuration, this means the four are free to wonder and find opportunity to PAIR UP with other atoms.
- That’s because The Octet Rule requires the valence shell or outermost shell of the atoms to have 8 electrons to become stable.
- You can read more about the Octect Rule here. octet rule
When two carbon atoms come together, they can each share 1 electron and form a single bond. That will leave three valence electrons from each atom to pair up with other electrons from other atoms they come in contact with.
CARBON TO CARBON SKELETAL STRUCTURES
The skeletal structure shows the type of bonding between elements.
SINGLE, DOUBLE AND TRIPLE BONDS
Single bond — 1 atom shared from each atom
Double bond — 2 atoms shared from each atom
Triple bond — 3 atoms shared from each atom
DRAWING A LINE IN THE MIDDLE
Here’s a trick – if you draw a line through the middle of the carbon bonds, you should be able to work out exactly 4 bonds on each side, because each carbon atom has 4 bonding electrons which are the valence electrons.
