Chemistry cheat sheet
Organic chemistry is the study of compounds that are based on carbon - organic compounds.
They usually contain carbon-carbon and carbon-hydrogen bonds.
The exceptions - carbon monoxide, CO(g), carbon dioxide, CO2 (g), and hydrogen cyanide, HCN(g).
Molecules that contain only single carbon-carbon bonds are saturated - alkanes.
Molecules that contain double or triple carbon-carbon bonds are unsaturated - alkenes and alkynes.
Carbon’s unique bonding properties allow the formation of a variety of structures, including chains and rings of many shapes and sizes.
