Understanding E/Z Configuration in Alkenes

Why is the cis/trans terminology insufficient for alkenes with four different substituents?

• It is a relative terminology and cannot provide a unique name.

• It requires the use of German words.

• It only applies to alkenes with identical substituents.

• It is only used for alkanes.

What is the first step in determining the E/Z configuration of an alkene?

• Determine the molecular weight of the alkene.

• Count the number of hydrogen atoms.

• Assign priorities based on atomic number to the groups attached to each carbon of the double bond.

• Identify the longest carbon chain.

What does the 'Z' in Z configuration stand for?

• Zusammen, meaning together

• Zentrum, meaning center

• Zahlen, meaning numbers

• Zukunft, meaning future

When comparing two identical carbon atoms in a chain, what should you do next?

• Choose the one with more hydrogen atoms.

• Pick the one with a longer chain.

• Continue down the chain until a point of difference is found.

• Select the one with a higher molecular weight.

How is the E/Z configuration incorporated into the IUPAC name of a molecule?

• By using it as a prefix to the substituents.

• By adding it as a suffix to the name.

• By placing it in parentheses before the IUPAC name.

• By including it in the middle of the name.
