Document Summary
Organic compounds also contain h, n, o, p, s, cl . Organic chemistry was first (and wrongly!) defined in 1770: compounds from living organisms, contain vital force that can"t be made in the lab. W hler made urea (found in urine) from an inorganic salt: Not very electronegative (shares well, makes strong covalent bonds) Can make long c-c chains or rings (biological molecules can have from 1 c to millions!) C can make up to four bonds. http://www. columbia. edu/cu/opg/images/dna. jpg. Dashed lines indicate a bond sticking back behind the plane. Wedges indicate a bond sticking out in front of the plane. Each line segment represents a c at each end. H"s are omitted, but we know that c has 4 bonds so we can figure it out. We do not put a c where we know there is a carbon atom. Nature of the atom: hydrogen and hydrogen-like orbitals.
