  • Structural Formula
    Illustrates the connectivity between atoms in a molecule, showing all bonds explicitly.
  • Expanded Formula
    A detailed representation of a molecule where every bond is shown.
  • Condensed Formula
    A compact representation of a molecule where bonds are implied rather than shown.
  • Skeletal Formula
    A simplified organic molecule representation where carbons and hydrogens are not shown.
  • Kekule Structure
    Another term for skeletal formula, emphasizing carbon invisibility.
  • Tetravalent
    Describes an atom, like carbon, that forms four bonds to achieve stability.
  • Pentane
    An organic compound with the molecular formula C5H12, often used to illustrate structural formulas.
  • CH3 Group
    A methyl group consisting of one carbon atom bonded to three hydrogen atoms.
  • CH2 Group
    A methylene group consisting of one carbon atom bonded to two hydrogen atoms.
  • Ball and Stick Model
    A 3D molecular model where atoms are represented by balls and bonds by sticks.
  • Molecular Formula
    A notation indicating the number and type of atoms in a molecule, without structural details.
  • Connectivity
    The specific arrangement and bonding of atoms within a molecule.
  • Organic Molecule
    A compound primarily composed of carbon atoms bonded with hydrogen, oxygen, or other elements.
  • Halogen
    A group of elements including fluorine, chlorine, bromine, and iodine, often bonded to carbon.
  • Lewis Structure
    A diagram showing the bonding between atoms and the lone pairs of electrons in a molecule.
