A compound containing carbon and hydrogen only.
A series of organic compounds with the same functional group but with each successive member differing by CH2.
A group of atoms that are responsible for the characteristic reactions of a compound
Contains single C-C bonds
Containing at least one carbon to carbon multiple bond
The simpliest whole number ratio of atoms of each elements present in a compound
The actual number of atoms of each element in a molecule
Compounds with the same molecular formula but with a different structural formulae
Compounds with the same structural formula but with a different arrangement of atoms in space
An example of stereoisomerism in terms of restricted rotation about a double bond and the requirement for two different groups to be attached to each carbon of the C--C group
A special case of E/Z isomerism in which two of the substituent groups are the same
The breaking of a long chained saturated hydrocarbon to form more useful alkanes (shorter chained) and alkenes.
A fuel that is derived from recently living material such as plants or the waste of animals
A reactive species with an unpaired electron
The breaking of a covalent bond where the shared pair of electrons are split equally forming two radicals
Heat is given out to the surroundings (the reactants loose energy)
Heat is taken from the surrounding, the reactants gain energy
the minimum enery required to start a reaction by the breaking of bonds
A pressure of 1 atmosphere, a stated temperature usually 25^c and a concentration of 1 mole.
Standard Enthalpy Change of Reaction
The enthalpy change that accompanies a reaction in the molar quantities expressed in the chemical equation (under standard conditions, all reactants and products are in their standard states)
Standard Enthalpy Change of Formation
The standard enthalpy change that takes place when one mole of a compound is formed from its constituent elements (in their standard states under standard conditons)
Standard Enthalpy Change of Combustion
The standard enthalpy change that takes place when 1 mole of a compound reacts completely with oxygen ( all products are in their standard states under standard conditons)
Average Bond Enthalpy
The average enthalpy change is required to break 1 mole of a gaseous covalent bond by homolytic fission.
Speeds up a reaction without being consumed in the overall reaction.
