Fichas del conjunto (15)
- 1Free RadicalHighly reactive single atom or group of atoms with unpaired electrons.
- 2NucleophileIons or molecules with a lone pair of electrons that attack positive ions or positive centres in molecules.
- 3ElectrophileReactive ions or molecules which attack negative ions or centres in molecules.
- 4Homolytic fissonThe equal share or electrons in the covalent bond, so when the bond breaks both atoms each take one electron. This produces free radicals.
- 5Heterolytic fissionAn unequal share of electrons in the covalent bond, so when the bond breaks one atom will be negatively charged (as it has gained an electron) and the other atom will be positively charged (as it has lost an electron).
- 6Chain isomerismWhere the carbon arrangement is varied for the same molecular formula.
- 7Positional isomerismWhere the position of a functional group or substituent differs, but it still gives the same molecular formula.
- 8Functional Group isomerismWhere a different functional group is present, but it still gives the same molecular formula.
- 9Geometric isomerismTakes place when a double bond is present and there is restricted rotation around the double bond.
- 10StereoisomerismWhere atoms are connected in the same order, but with a different arrangement in space.
- 11Molecular formulaThe number of atoms of different elements in one molecule of a compound.
- 12Display formulaShows all of the atoms and all of the bonds between them in one molecule of a compound.
- 13Structural formulaShows which atoms or groups of atoms are attached to each other. Can also be represented by drawing the display formula as it shows what atoms are attached to each other.
- 14Empirical formulaThe simplest whole number ratio of the atoms of different elements in a compound.
- 15Skeletal formulaShows the functional group fully, but the hydrocarbon part simply as lines between carbon atoms, omitting the symbols for hydrogen and carbon atoms.
