Rules of Drawing Line-Angle Formulas Bonds are represented by lines Assume carbon atoms at the ends of lines and where they meet Assume enough C-H bonds to give each carbon atom four bonds(octet) Carbon and hydrogen atoms are only drawn at termini for aesthetics Draw heteroatoms and attached hydrogen atoms(N,O,P,CI,Br,F,I,etc.) ◆(any atom that is not carbon)】 H H OH OH H G C C H H HgC CH3 HH H H C. H-C C-H HO-C CH3 Don't forget about H- the implied Incorrect! H hydrogen atoms! (Why?) Always show all lone pairs! (helps with electron bookkeeping)
