What is Multiple Covalent Bonding?
- It is exactly the same as a normal single covalent bond except there is more than one spare electron for each atom, meaning that it has to make two or possibly more coalent bonds so that it can have a full outer shell.
Double Covalent Bonding in an Oxygen Molecule:
- Oxygen has only 6 electrons in its outer shell so it would need 2 more to complete the shell.
- Consequently, 1 covalent bond would not fill the shell so 2 covalent bonds are needed.
- One atom joins with another oxygen atom and makes 2 covalent bonds.
- This molecule would look like this when drawn:
