Which of the Following Statements Concerning Conformational Isomers Is FALSE

Which of the following statements concerning conformational isomers is FALSE?

A) Conformational isomers are different spatial arrangements of the same molecule,formed by rotation around single bonds.
B) Conformational isomers rapidly interconvert,and cannot be physically separated from each other.
C) The staggered and the eclipsed conformation are two types of conformational isomers of alkanes.
D) The staggered conformation is more stable than the eclipsed conformation,because in the staggered conformation electron repulsion is maximized.
E) The boat conformation and the chair conformation are two conformational isomers of cyclohexane; the chair conformation is the more stable of the two.
