CHEMISTRY - batch 6

yield

Measure of the extent of the reaction, generally measured by comparing the amount of product against the amount of product that is possible.

Saturated compound

A compound in which all the bonds between carbon atoms are single bonds

Unsaturated compound

A compound in which there is at least one double and/or triple bond between carbon atoms.

Functional group

An atom or group of atoms that form the centre of chemical activity in the molecule.

(structural) isomers

Compounds having the same molecular formula but different structural formulae

Substitution reaction

Reactions where one atom or molecular fragment is replaced in a molecule by another

Elimination reactions

Where atoms or molecular fragments are removed from the adjacent carbon atoms on a molecule leaving a double bond with nothing else having been added.

Addition reactions

Where a double bond opens and new molecular fragments are added to the molecule at both ends of the double bond without anything being removed.

Heat of reaction

The net change of chemical potential energy of the system

Exothermic reactions

Reactions which transform chemical potential energy into thermal energy
