Document Summary

Chem 261 introductory organic chemistry i (adapted from prof. c. cairo"s notes) Suggested text problems: all non-starred questions in chapter, exclude problem 1-13: structure and bonding. Chemistry of life - fundamental to all biology, biochemistry and medicine. In addition to carbon, the key elements we will study in organic chemistry are: h, o, n, f, cl, br, s, p, i. The organic chemists periodic table: these few elements are the major components of living matter. For example, the human body (excluding water) is composed primarily of c (50%), o (20%), h (10%), n (8. 5%), p (2. 5 %), ca (4. 0%), Atomic structure - the atomic model: the electron cloud is the area in space where the electron is likely to be found. This is only a probability: the majority of the mass of an atom is in the nucleus. The electrons are the business end of the atom. The bonding and interactions of atoms and molecules are mediated by electrons.
