• Molecules with the same structural formula but a different spatial arrangement of atoms

• Molecules with different molecular formulas but the same structure

• Molecules with different structural formulas and different spatial arrangements

What is the definition of stereoisomerism?

• Molecules with the same structural formula but a different spatial arrangement of atoms

• The carbon chain length

• The type of functional group

• The spatial arrangement of atoms

What is functional group isomerism?

• Compounds with the same molecular formula but a different functional group

What does the 'Z' in E-Z isomerism stand for?

• Zusammen (together)

• Zwitterion

According to the Cahn-Ingold-Prelog priority rules, what determines the priority of groups attached to a C=C bond?

• Atomic numbers of atoms attached to the C=C

• Molecular weight of the compound

• Length of the carbon chain

• Number of hydrogen atoms

In the Cahn-Ingold-Prelog system, what does it mean if the highest values are opposite?

• The isomer is designated as E

• The isomer is designated as Z

• The isomer is a chain isomer

• The isomer is a functional group isomer
