Lecture 3 I. Biological importance of Carbon In organic compounds, carbon is bonded to hydrogen or another carbon Carbon backbone: a basic skeleton of the structure of a carbon. Can vary in four ways o Length o Branching o Double-bond position o Presence of rings Skeleton properties affect molecular geometry Recall: valence electrons dictate bonding properties o Hydrogen carries 1 valence electron o Oxygen carries 2 valence electrons o Nitrogen carries 3 o Carbon carries 4 A. Hydrocarbons Organic molecules composed of carbon and hydrogen Nonpolar, uncharged, nonionic Hydrophobic (hates water) Can contain functional groups If
