The Chair and Boat Conformations of Cyclohexane Are Shown Below

question 4

Multiple Choice

The chair and boat conformations of cyclohexane are shown below.Which statement best explains why the chair conformation is more stable than the boat conformation?

• A)The hydrogen atoms in the chair conformation are all staggered,which minimizes the repulsion of the bonding electrons.
• B)The carbon atoms in the chair conformation are all eclipsed,which provides for the ideal bond angle of 109.5°.
• C)The carbon atoms in the chair conformation are closer together than in the boat conformation,which provides for stronger C-C bonds.
• D)The hydrogen atoms in the chair conformation are closer together than in the boat conformation,which provides for stronger C-H bonds.
• E)The C-C bonds in the chair conformation are all staggered,which maximizes the energy of the molecule.
