Document Summary

26: hydrogens are usually connected to their preceding non - hydrogen atom. H- c - c - c - h. =25 valence electrons: an entire group in parentheses will branch off from the main chain and attach to the prior non- hydrogen atom. H- c - c - q - c- c - h. * parentheses arent always shown in condensed formulas. H - c - c=c- c - h ti ti. Groups in parentheses branch off the main chain . H- c - c - o- c - c - h.
