Textbook Question
Chapter 12, Problem 12.34P
If you examine the structural formulas for the following cycloalkenes, you will see that the configuration of the double bond is cis in each.
Cyclopentene Cyclohexene Cycloheptene
All attempts to synthesize these cycloalkenes in which the double bond has a trans configuration have failed. Apparently, it is impossible to have a
trans configuration in these cycloalkenes. Offer an explanation for why this is so.

Conformational isomers are enantiomers or diastereomers, which can interconvert through rotations around bonds within molecules, which include anti and gauche butane. Stereoisomers have the same connectivity but different arrangement of their parts in space, which include enantiomers, diastereomer, and conformational isomers, which include cis and trans dichlorocyclobutane. O Structural or constitutional isomers are molecules of the same formula but different connectivity such as 1,1-dichlorocyclopropane and 1.2-dichlorocyclobutane.arrow_forward
