Ethylene (C2H4) is a colorless, flammable gas with a sweet-musky odor. It occurs naturally in petroleum and natural gas. Used as a monomer for polyethylene synthesis and as a starting material for ethanol and styrene
Organic compounds contain carbon-hydrogen or carbon-carbon bonds. Some authorities consider all carbon-containing compounds organic. Vitalism was once believed organic compounds formed from elements. Modern definition excludes certain traditionally considered inorganic compounds
Carbon trioxide (CO3) is an unstable oxide of carbon. Three possible isomers exist: Cs, D3h, and C2v. C2v state (dioxirane) is the ground state of the molecule. D3h isomer first detected in electron-irradiated CO2 ices
CCl4 is a tetrahedral compound with a central carbon surrounded by 4 chlorine atoms. Carbon has 4 lone electrons, chlorine has 7 electrons. Carbon shares its 4 outer electrons with chlorine atoms
PH3 contains three single bonds between phosphorus and hydrogen atoms. Phosphorus is at center surrounded by three hydrogen atoms. Phosphorus has one lone pair
Chemical structure drawing illustrates compound elements using symbols and diagrams. Common symbols include circles, squares, diamonds, lines, and atom labels. Allows chemists to communicate ideas in universal language
