an algebraic formula that can describe any member of a family of compounds.

the simplist ratio of atoms of each element in a compound

the actual number of atoms of each element in a molecule

the molecular formula rearranged to show the atoms attached to each carbon atom in a chain

it shows the carbon bonds and where any atoms or groups of atoms (apart from hydrogen) are attached.

a diagram showing how atoms and bonds are arranged in space

a group of molecules with the same functional group that can be representing by the same general formula.

the reactive part of a molecule, which gives it its properties

meth eth prop but pent hex hept oct non dec undec dodec

a system for naming organic compounds agreed internationally

diagrams to show individual stages of a reaction

they show where a pair of electrons comes from and goes in a reaction

a molecule with the same molecular formula, but a different arrangement in space

structural and stereo

chain, positional and functional group

isomers with different arrangements of the carbon skeleton

isomers with the same carbon skeleton, but a different place that an atom/ group of atoms is attached

isomers that have the same atoms, that are arranged into different functional groups

isomers with the same structural formula, but a different arrangement in space

the carbon double bond can’t rotate, so branches connected to these carbon atoms can be oriented in two different directions

the two possibilities of stereo isomerisms

the isomer with the highest priority branches arranged diagonally

the isomer with the highest priority groups on the same side

the branch with the highest atomic number is given priority

geometric isomerism
