Document Summary

Chemistry is the study of the structure and function of molecules and the rules that govern their interaction. What is organic chemistry: study of carbon-based compounds, synthesis of molecules, study of physical properties or organic compounds, study of physical structure of organic compounds, have distinct shape and architecture, study is experimental and computational. Organic molecules contain various subunits that control the reactivity: called functional groups. Valence shell: the outermost shell of electrons surrounding an atom. Atoms gain or lose valence electrons to achieve noble gas configuration. Octet rule: elements want eight valence electrons. Valence shell electrons can be used to predict behavior atoms. Ionic bonding: electrons are transferred: large difference (>2) in pauling electronegativity. Chemical compound in which the component atoms exist as ions is an ionic compound. Lewis: an atom is most stable if it has a filled outer shell (isoelectronic with a noble gas)
