From what I've found, this exam is very attention to detail.
Make sure you state where your double bond is... make sure you cover every point in the statement, and learn your definitions! Every year at least two have come up. The definitions that you need to know are:
Enthalpy Change of Reaction: The number of moles of reactant as specified in the balanced equation react together.Enthalpy Change of Combustion: The enthalpy change that takes place when 1 mole of compound COMBUSTS (NOT BURNS) completely with oxygen under standard conditions, all reactants and products being in their standard states.
The Enthalpy Change of Formation: The enthalpy change that takes place when 1 mole of compound is formed from its constituent elements
in their standard state under standard conditions.Radical- Species with an unpaired electron
Electrophile- Electron pair acceptor
Nucleophile- Electron Pair Donor
Average Bond Enthalpy- The
average enthalpy change that takes place when breaking by homolytic fission 1 mole of a given
type of bond of a molecule of gaseous species.Activation Energy- The minimum energy
needed for the reaction to start by the breaking of bonds.Le Chatelieur Principle:
The position of the equilibrium will shift to minimise the effect of any change in condition.Functional Group- An atom/group of atoms responsible for the chemical properties of the compound and its reactions.
Homologous Series: Group of Organic Molecules with the same functional group and each successive member differing by CH2
Empirical Formula: The simplest whole number ratio of atoms of each element present in a compound.
General Formula: Simplest algebraic formula of a member of a homologous series.
Molecular Formula: The actual number of atoms of each element present in a compound
Structural Formula: Shows the minimal detail that shows the arrange of atoms in a molecule.Displayed Formula:
The relative positioning of the atoms and the bonds between them.Skeletal Formula-
Simplified organic formula shown by removing all the hydrogen atoms from alkyl chains, leaving just a carbon skeleton with associated functional groups.Any More i've missed be sure to add them up
good luck everyone
