| Term | Definition |
| covalent bond | a chemical bond that involves sharing a pair of electrons between atoms in a molecule |
| double bond | a covalent bond in which two pairs of electrons are shared between two atoms |
| triple bond | a bond between two carbon atoms in which 6 electrons (or 3 pairs of electrons) are shared |
| polar bond | where one element attracts the shared electrons much more strongly than the second potassium |
| ionic bond | atoms linked together by the attraction of unlike charges usually w/nonmetal + metallic elements. one has a slightly positive charge, the other a slightly negative charge |
| hydrogen bond | very weak bonds; occurs when a hydrogen atom in one molecule is attracted to the electrostatic atom in another molecule |
| metallic bond | atoms linked together by the migration of electrons from atom to atom, like in electricity |
| hydrocarbon | a molecule made up of only hydrogen and carbon |
| alkane | a hydrocarbon w/o a double bond, triple bond or ring structure |
| alkene | a hydrocarbon w/one or more double bonds and no triple bonds for the purposes of hembry's tests, all of these will have only one double bond |
| alkyne | a hydrocarbon w/one or more triple bonds for the purposes of hembry's tests, all of these will have only one triple bond |
| isomer | a molecule with a different structure "isomers of each other" |
| cyclo- | a prefix meaning the carbons in the hydrocarbon are arranged in a circle |
| meth | 1 carbon per hydrocarbon |
| eth | 2 carbons per hydrocarbon |
| prop | 3 carbons per hydrocarbon |
| but | 4 carbons per hydrocarbon |
| pent | 5 carbons per hydrocarbon |
| hex | 6 carbons per hydrocarbon |
| hep | 7 carbons per hydrocarbon |
| oct | 8 carbons per hydrocarbon |
| non | 9 carbons per hydrocarbon |
| dec | 10 carbons per hydrocarbon |
