Heat of Condensation

The amount of heat that must be removed from one gram of a vapor at it's condensation point to condense the vapour with no change in temperature.

Hydrolysis Constant

An equilibrium constant for a hydrolysis reaction.

Unsaturated Hydrocarbons

Hydrocarbons that contain double or triple carbon-carbon bonds.

Galvanizing

Explosive limits

The range of concentrations over which a flammable vapour mixed with proper ratios of air will ignite or explode if a source of ignitions is provided.

Conformations

Structures of a compound that differ by the extent of rotation about a single bond.

Derivative

A compound that can be imagined to arise from a partent compound by replacement of one atom with another atom or group of atoms. Used extensively in orgainic chemistry to assist in identifying compounds.
