question 63

Multiple Choice

Which of the following statements about the conformations of acyclic alkanes is true?

• A)Conformations are the same arrangements of atoms that cannot be interconverted by rotation about single bonds.
• B)In the eclipsed conformation,the C-H bonds on one carbon bisect the H-C-H bond angle on the adjacent carbon.
• C)In the staggered conformation,the C-H bonds on one carbon are directly aligned with the C-H bonds on the adjacent carbon.
• D)Rotating the atoms on one carbon by 60° converts an eclipsed conformation into a staggered conformation,and vice versa.
