When working with dash formulas atoms joined by single bonds can _______ relatively free with respect to one another
Each line represents bond
rule 1 for when drawing bond-line formulas
Each bend in a line or terminus of a line represents a carbon atom, unless another group is shown explicitly
Rule 2 for when drawing bond-line formulas
No letter C’s are written for carbon atoms, except optionally for CH3 groups at the end of a chain or branch
rule 3 for when drawing bond-line formulas
No letters H’s are shown for hydrogen atoms, unless they are needed to give a three-dimensional perspective, in which case we use dashed or solid wedges
rule 4 for when drawing bond-line formulas
The number of hydrogen atoms bonded to each carbon is inferred by assuming that as many hydrogen atoms are present as needed to fill valence shell of the carbon, unless a charge is indicated
Rule 5 for when drawing bond-line formulas
When an atom other than carbon or hydrogen is present, the symbol for appropriate location
Rule 6 for when drawing bond-line formulas
Hydrogen atoms bonded to atoms other than carbon are written explicitly
Rule 7 for when drawing bond-line formulas
