isomerism and E/Z isomerism

what is geometric isomerism?

• compounds/molecules w/ the same structural formula

• but atoms/bonds/groups arranged differently in space

what is stereoisomerism? give 2 examples:

compounds/molecules w/ the same molecular and same structural formula but a different arrangement of atoms in space:

• geometric isomerism

• optical isomerism

what are structural isomers? give 3 examples:

compounds/molecules with the same molecular formula but a different structural formula:

• chain isomerism

• position isomerism

• functional group isomerism

what are the 3 types of structural isomerism?

• chain isomer

• position isomer

• functional group isomer

whata chain isomer?

compounds/molecules w/ the same functional group and molecular formula but a different arrangement of the carbon chain

what is a position isomer?

compounds/molecules w/ the same molecular formula and carbon chain but w/ the functional group in a different place

what are functional group isomers?

compounds/molecules w/ the same no. of atoms but arranged to form a diff functional group

why does E-Z isomerism occur?

restricted rotation around the C=C double bond

give the 2 types of E/Z isomers:

• Z isomer (zusammen) = higher priority groups are on the same side of the C=C double bond

• E isomer (entgegen) = higher priority groups are on opposite sides of the C=C double bond

summarise the CIP priority rules:

C w/ the groups w/ the highest atomic number = highest priority
