Isomer

Molecules with the same molecular formula but have different molecular structures or a different arrangement of atoms in space

Stereoisomerism

Two or more compounds have the same structural formula but they differ in the arrangement of bonds in space

Optical isomerism

Occurs when four different substituents are bonded to one carbon atom resulting in two isomers that are non-superimposable mirror images of one another

Optical isomer

Pairs of molecules that are non-superimposable mirror images

Chiral

Handed

Chiral

A molecule that exists in two mirror image forms that are not superimposable

Enantiomer

One of a pair of non-superimposable mirror image isomers

Chiral centre (asymmetric carbon atom)

An atom to which four different atoms or groups are bonded. The presence of such an atom causes the parent molecule to exist as a pair of non-superimposable mirror images.

Polarimeter

Measures optical rotation

Racemate

A mixture of equal amounts of two optical isomers of a chiral compound, it's optically inactive

Carbonyl group

RCHO

Acid derivative

An organic compound related to a carboxylic acid of formula RCOZ, where Z \= —Cl, —NHR, —OR or —OCOR.

Inductive effect

The electronreleasing effect of alkyl groups such as -CH3 or -C2H5

Condensation reaction

A chemical reaction in which two molecules react together and a small molecule, often water or hydrogen chloride, is eliminated

Zwitterion

An ion that has both a permanent positive and negative charge, though the overall charge of the ion is neutral

Protonated

Describes an atom, molecule or ion to which a proton (H+ ion) has been added

Deprotonated

Describes an atom, molecule or ion to which a proton (H+ ion) has been lost
