6. Define functional group

  • a series of organic compounds with the same functional group but with each successive ember differing by CH2
  • the part of the organic molecule responsible for its chemical reactions
  • compounds with the same structural formula but with different arrangements of the atoms in space
  • a species with an unpaired electron

7. Define molecular formula

  • a formula shown the carbon skeleton an associated functional groups only
  • the simplest whole-number ratio of atoms of each element present in a compound
  • the number of atoms of each element in a molecule
  • CH3CH2CH2CH3

8. Define displayed formula

  • a formula showing the relative positioning of all the atoms in a molecule and the bonds between them
  • the simplest algebraic formula of a member of a homologous series
  • C2H4
  • the simplest whole-number ratio of atoms of each element

9. Define homolytic fission

  • C2H4
  • the breaking of a covalent bond with one of the bonded elections going to each atom to form 2 radicals
  • a species with an unpaired electron
  • the breaking of a covalent bond with both of the bonded electrons going to one of the atoms forming a cation (+ve) and an anion (-ve)

10. Define structural formula

  • the simplest whole-number ratio of atoms of each element present in a compound
  • C3H8
  • a formula showing the minimal amount of detail for the arrangement of atoms in a molecule

11. Define electrophile

  • an atom that is attracted to an electron-rich atom, where it accepts a pair of electrons to form a new covalent bond
  • when a molecule is removed from a saturated molecule to make an unsaturated molecule
  • an atom that is attracted to an electron-deficient atom, where it donates a pair of electrons to form a new covalent bond
  • a species with an unpaired electron

12. Define empirical formula

  • A formula shown the minimal detail for the arrangement of atoms in a molecule
  • The number of atoms of each element in a molecule

  • The simplest algebraic formula of a member of a homologous series

13. Define general formula

  • the simplest algebraic formula of a member of a homologous series
  • a series of organic compounds with the same functional group but with each successive member differing by CH2
  • a simplified organic formula, with hydrogen atoms removed from alkyl chains, leaving just a carbon skeleton and associated functional groups
  • the number of atoms of each element in a molecule
