Question

What is the relationship between the structures shown?

• A. $Structuralisomers$
• B. $Geometricisomers$
• C. $Conformationalstructures$
• D. $Identicalstructures$

Answer 1

Answer: (C)

$Conformationalstructures$

In chemistry, conformational isomerism is a form of stereoisomerism in which the isomers can be interconverted exclusively by rotations about formally single bonds (refer to figure on single bond rotation). Such isomers are generally referred to as conformational isomers or conformers and, specifically, as rotamers. From image it is clear that the bond is rotated and two structures and conformational structures.
