/* Structural formula */ Removed "Thus a simplified structural formula for acetic acid might look like the one at left." - therre is no drawing at left
The ''structural formula'' is an often elaborate two-dimensional drawing showing the relationship of the various atoms to one another. The structural formula for water would be H-O-H if one habitually used a structural formula to describe water.
The most elaborate type of structural formula would mention each and every atom in the molecule, including hydrogen. But commonly used structural formulas for organic compounds typically leave off any hydrogen atoms bound to carbon (and assume that hydrogen atoms are bound to any vacant positions on any carbon atoms), and represent the carbon atoms as corners in an angular drawing of the backbone of the molecule. Thus a simplified structural formula for acetic acid might look like the one at left.
Here one assumes that a carbon atom resides at the end of the backbone and at the center, with three hydrogen atoms occupying the vacant spaces on the carbon atom at the end.
