Drawing Structural Formulas in Line Notation

Procedure

To draw line notation structural formulas for covalent compounds

1. Consider number of bonds for each element using table below and H=1 bond
Group #IVAVAVIAVIIAVIIIA
#e in OEL
(Bohr Orbit)
45678
# bonds
formed
43210

2. Bond together those elements that form more than one bond

3. Place hydrogens or Group VII elements around unfilled bond sites

4. If not enough hydrogens, then use multiple bonds

5. May need to rearrange some H's or VII's after adding multiple bonds in order so satisfy item 1 above.
