Question

Stereoisomers ( different arrangements of atoms) that can be converted into one another by roatation about single bonds are called
A. enantiomers
B. conformers
C. diasteromers
D. aromers

Answer 1

Correct Answer - B
Also called conformations or rotamers, they are temporary molecular shapes that result form the rotations of group about single bonds. An analysis of the energy changes that a molecule undergoes as group rotate about single bonds is called conformational anaysis. The term conformer is normally used for low energy conformations.
