1
what are mechanism diagrams
diagrams to show individual stages of a reaction
2
what are iupac rules
a system for naming organic compounds agreed internationally
3
explain how stereo isomers exist
the carbon double bond can’t rotate, so branches connected to these carbon atoms can be oriented in two different directions
4
what is the e isomer
the isomer with the highest priority branches arranged diagonally
5
what is skeletal formula
it shows the carbon bonds and where any atoms or groups of atoms (apart from hydrogen) are attached.
6
what are the three types of structural isomer
chain, positional and functional group
7
what is a functional group
the reactive part of a molecule, which gives it its properties
8
what is general formula?
an algebraic formula that can describe any member of a family of compounds.
9
what is a isomer
a molecule with the same molecular formula, but a different arrangement in space
10
using the Cahn-Ingold-Prelog priority rules, how do you decide priority
the branch with the highest atomic number is given priority
11
what is displayed formula
a diagram showing how atoms and bonds are arranged in space
12
what are stereoisomers
isomers with the same structural formula, but a different arrangement in space
13
what are positional isomers
isomers with the same carbon skeleton, but a different place that an atom/ group of atoms is attached
14
what do the curly arrows in mechanism diagrams mean
they show where a pair of electrons comes from and goes in a reaction
15
what are chain isomers
isomers with different arrangements of the carbon skeleton
16
what is a homologous series
a group of molecules with the same functional group that can be representing by the same general formula.
17
what is another name for e/z isomerism
geometric isomerism
18
list the prefixes
meth eth prop but pent hex hept oct non dec undec dodec
19
what are the two main types of isomer
structural and stereo
20
what is molecular formula
the actual number of atoms of each element in a molecule
21
what is structural formula
the molecular formula rearranged to show the atoms attached to each carbon atom in a chain
22
what is empirical formula?
the simplist ratio of atoms of each element in a compound
23
what are functional group isomers?
isomers that have the same atoms, that are arranged into different functional groups
24
what is the z isomer
the isomer with the highest priority groups on the same side
25
what are E/Z isomers
the two possibilities of stereo isomerisms
