    Each of two or more different physical forms in which an element can exist. Graphite, charcoal, and diamond are all allotropes of carbon
  2. Alkane
     Any saturated aliphatic hydrocarbon with the general formula CnH2n+2
  3. Alkene
    Any of a series of unsaturated, open chain hydrocarbons with one or more carbon-carbon double bonds, having the general formula CnH2n
  4. Alkyne
    any unsaturated aliphatic hydrocarbon that has a formula of the type CnH2n-2
  5. Isomer
    Any of two or more substances that are composed of the same elements in the same proportions but differ in properties because of differences in the arrangement of atoms.
  6. Functional Group
    An atom or group of atoms, such as a carboxyl group, that replaces hydrogen in an organic compound and that defines the structure of a family of compounds and determines the properties of the family.
