Lewis Structures for Molecules with Multiple Bonds
After applying Steps 1-4, there may not be enough electrons for
the central atom (or one of the central atoms) to attain an octet.
This situation suggests that a multiple bond (bond order of 2 or 3)
is present in the molecule.
STEP 5: If, after Step 4, a central atom still does not have an octet,
make a multiple bond by changing a lone-pair from one of the
surrounding atoms into a bonding pair to the central atom.
