- The reaction in which many small molecule monomers bond together to form a long chain polymer.
- A reaction in which at least two molecules combine together to form a larger molecule.
- Organic compounds contains the functional group -OH. The first four members of a homologous series of alcohols are methanol, ethanol, propanol and butanol. They can be oxidised to form carboxylic acids and dehydrated to alkenes.
- Able to be broken down by living organisms.
- Organic compounds combating the functional group -COOH. The first four members of a homologous series are methanoic acid, ethanoic acid, propanoic acid and butanoic acid, they have typical acidic properties.
- Reactions in which monomers join together and lose small molecules, such as water. These reactions involve monomers with two functional groups.
- Molecule which encodes genetic instructions for the development and functioning of living organisms and viruses. Most DNA molecules are two polymer chains, made from four different nucleotides, in the form of a double helix.
- The product of a condensation reaction between carboxylix acid and alcohol. For example: ethanol + ethanoic acid -> ethyl ethanoate.
- A chemical process by which molecules such as glucose are broken down anaerobically. Ethanol is produced when sugar solutions are fermented using yeast.
- A device used in flame photometry to identify the concentration of metal ions in a sample.
- An instrumental method used to analyse metal ions in solutions, the sample is put into a flame and the light given out is passed through a photometer. The output is a line spectrum that can be analysed to identify the metal Ions in the solution and measure their concentrations.
- Qualitative test used to identify cations, carried out by inserting a nichrome wire loop with the unknown compound on into a flame and observing the colour.
- The group of atoms responsible for how a particular compound reacts. All compounds in the same homologous series have the same functional group.
- Methods that are used to detect and identify elements and compounds. They are accurate, sensitive and rapid.
- Particles with diameters between 1 nm to 100 nm in size. Nanoparticles can exhibit properties different to those for the same material in bulk.
- The monomers which make up DNA.
- A category of polymers which contain the ester functional group in their main chain. Formed by a condensation reaction between a foil and a dicarboxylic acid.
- Polymers made up of amino acid molecules.
- Identification of the elements, ions or functional groups present in a compound.
- A hydrocarbon compound containing only single bonds between carbon atoms, such as alkanes.
- A polymer based on sugars.
- A compound that contains double or triple carbon bonds so that is contain the maximum number of hydrogen atoms, like alkenes.
