  1. 7. These are chiral molecules that are mirror images of each other. These molecules cannot be superimposed on one another. This then meaning that it is not possible for the molecules to placed on top of one another and give the same molecule.
  2. 10. This is when an equal action of opposing forces of a state of rest or balance occurs. Causing a equal balance between powers and influences. This can be where reactants and products in a chemical are in concentration to have no further tendency to change.
  3. 12. the positive carbon is attached to three alkyl groups. It the most stable.
  4. 14. configuration inversion observed during Sn2 reaction of a substrate in which the carbon containing the leaving group is chiral
  5. 15. This term refers to an object or molecule having lack of symmetry or not possessing symmetry at all.
  6. 17. A unimolecular reaction occurs when a molecule rearranges itself to produce one or more products.
  7. 19. Energy is transferred to or from the atmosphere. This is a reaction that has an overall standard enthalpy change that is ΔH⚬ which is negative. This reaction releases heat.
  8. 22. In chemistry this is known as a chemical reaction one function group in a compound is replaced by another function group. This reaction is significant in organic chemistry.
  9. 23. An atom or molecule which seeks a positive centre in a chemical reaction. An example being the nucleus of a atom. Containing an electron pair which is available to donate for bonding.
  10. 24. This type reaction refer to chemicals that combine, which consist of two molecules. The reaction is considered to be either reversible or irreversible. Involving two chemical distinct molecules or two identical molecules.
  11. 25. the stabilising interaction that occurs from the interaction of sigma bonds in C-H and C-C with either empty or partially filled p-orbitals which increases the stability of the system

  1. 1. one structural isomer is produced when other isomers are also possible. Happens due to stability.
  2. 2. An empirical rule for predicting the favoured alkene products in elimination reactions.
  3. 3. involving a single molecule
  4. 4. when two or more reactants join together to make a product without losing any atoms present in the reactants.
  5. 5. a 50:50 mix of retention and
  6. 6. A reaction which occurs by a free radical mechanism and results in the substitution of one or more of the atoms or groups present in the substrate by different atoms or groups.
  7. 8. A reactant that accepts a pair of electrons so it can Make A New Covalent Bond.
  8. 9. when two substituents are taken away from a molecule in a one or two step mechanism.
  9. 11. This refers to the minimum energy that is needed for a reaction to occur. This then means that the reactant molecules have enough kinetic energy to collide successfully and also to overcome any repulsion that may be caused by outer electrons.
  10. 13. the process of reversing the configuration of a chiral compound, referred to as ‘_____ of chemistry’
  11. 16. when the carbon skeleton of one molecule is arranged differently to give a structural isomer of the molecule.
  12. 18. process that favours bond formation at a particular atom over other atoms
  13. 20. Any process with an increase in the enthalpy H of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
  14. 21. This refers to the sum of the Internal energy (U) and the pressure and volume (PV) product . The equation can be written as
