Practice Problem: Newman Projections and Nomenclature

What are the two main tasks to be accomplished in the problem discussed?

• Drawing a Fischer projection and identifying functional groups

• Drawing a Newman projection and naming the molecule with stereochemistry

• Drawing a Newman projection and determining the molecular weight

• Drawing a Lewis structure and naming the molecule

In a Newman projection, what does the circle represent?

• The hydrogen atoms

• The entire molecule

• The front carbon

• The back carbon

When naming a molecule, why is the hydroxyl group given priority in numbering?

• Because it is the heaviest atom

• Because it is the most common group

• Because it is the highest priority functional group

• Because it is the largest group

Which substituents are present on the molecule discussed in the video?

• Propyl and hydroxyl groups

• Ethyl and hydroxyl groups

• Methyl and propyl groups

• Methyl and ethyl groups

What is the correct name of the molecule including stereochemistry?

• 3S, 4S, 4-ethyl-2-methyl-3-heptanol

• 3R, 4R, 4-ethyl-2-methyl-3-heptanol

• 3S, 4R, 4-methyl-2-ethyl-3-heptanol

• 3R, 4S, 4-ethyl-2-methyl-3-heptanol

How is the priority of groups determined for stereochemistry?

• By the size of the groups

• By the number of hydrogen atoms

• By the atomic number of the atoms directly attached

• By the length of the carbon chain

What is the configuration of the chiral center at carbon 3?

• R

• Both R and S

• Neither R nor S

• S
