| A | B |
| addition reaction | Reaction where monomers with double bonds add onto each other forming long chains. |
| alkane | saturated hydrocarbon that consists of single bonds between all atoms. |
| alkene | hydrocarbon with one or more double bonds. |
| alkyne | unsaturated hydrocarbon that has one or more triple bonds. |
| aromatic hydrocarbon | contains a benzene ring with distinct odors. |
| condensation reaction | a polymer that is formed when water is given off between each bonding monomer pair, linking them into in a polymer chain. |
| craking | in the absence of air, a catalyst is used to break down or rearrange large hydrocarbons. |
| cross-linking | When links between polymer chains occur, linking them into a stronger substance. |
| fractional distillation | a repeated vaporization-condensation cycle used to separate out via distillation. |
| functional group | a group that imparts specific behavior of the molecule is becomes bonded to. |
| isomer | molecule of same formula but with different arrangements. |
| monomer | small units of a polymer. |
| polymer | large molecule composed of small repeating units. |
| saturated hydrocarbon | hydrocarbon composed of all single bonds. |
| thermopastic | a plastic that will soften and harden repeatedly when heated and cooled. |
| unsaturated hydrocarbon | hydrocarbon containing one or more double or tripe bonds. |
