Unformatted text preview: Look for 4 total bonds on all carbon atoms, three on all nitrogen atoms, and two on all oxygen atoms to determine whether additional hydrogen atoms are present. Note that the wedges and dashes that were drawn on the board in the first lecture have been omitted (but they will return soon enough. ..). Do not let the apparent complexity of the larger molecules get to you! They are no more difficult that the simple molecules if you follow the rules. You do not have to remember the specific names, structures, or functions of these molecules for any exams in this class. Lecture 1 Practice Problems: Reading Organic Structures O O OH HO HO HO...
