Alkanes Hydrocarbons are compounds containing hydrogen and carbon only There are four families of hydrocarbons you should know: alkanes, alkenes, alkynes and arenes Alkanes have the general molecul...
Nomenclature Systematic nomenclature can be used to name organic compounds and therefore make it easier to refer to them The alkanes provide the basis of the naming system and the stem of each name...
Representing Formulae Organic compounds can be represented in a number of ways: Empirical Formulae Molecular Formulae Structural Formulae Condensed Structural Formulae The empirical formula shows t...
Homologous Series Organic chemistry is the chemistry of carbon compounds Carbon forms a vast number of compounds because it can form strong covalent bonds with itself This enables it to form long c...
Electrolytic Cells An ionic compound conducts electricity when it is molten or in solution The current causes the ionic compound to split up and form new substances. This process is called electrol...
Voltaic Cells Voltaic (or Galvanic) cells generate electricity from spontaneous redox reactions For example: Zn (s) + CuSO4 (aq)→ Cu (s) + ZnSO4 (aq) Instead of electrons being transferred direct...
The Winkler Method The Winkler Method is a technique used to measure dissolved oxygen in freshwater systems Dissolved oxygen is used as an indicator of the health of a water body, where higher diss...
Redox Titrations In a titration, the concentration of a solution is determined by titrating with a solution of known concentration. In redox titrations, an oxidizing agent is titrated against a red...
The Activity Series Metals can be ranked in order of reactivity -this is called the reactivity series or just activity series Metals higher in reactivity can displace less reactive metals from thei...
