Document Summary
The physiology of every organism is governed by organic chemistry. Most biomolecules are huge organic molecules, and so we will start small and work our way up. Organic chemistry study of compounds that have a carbon skeleton also contain other atoms with h, n, o and sometimes halogens how many valence electrons for. Neutral c makes 4 bonds and only 4 bonds, never more and never less. Neutral n makes 3 bonds and only 3 bonds, never more and never less. Neutral o makes 2 bonds and only 2 bonds, never more and never less. Neutral h makes 1 bond and only 1 bond, never more. Although our te(cid:454)t list properties of a (cid:862)t(cid:455)pi(cid:272)al(cid:863) orga(cid:374)i(cid:272) (cid:272)o(cid:373)pou(cid:374)d, due to the i(cid:374)(cid:272)redi(cid:271)le (cid:448)ariet(cid:455) of compounds, there really is no such thing! (cid:862)like dissol(cid:448)es like(cid:863) water = polar. There are three allotropic forms of elemental carbon. Tetrahedral: ethane (c2h6) combines two of the methane structures - two tetrahedrals.
