Isomer of C four H eight
A book mentioned that one of the isomers of C four H eight (butene) is cyclobutane. How is it possible?
Cyclobutane consists of 4 -CH2- units in corners of a rectangle, the corners are linked along sides of the retangle. Isomers needn't to have the same structure. Isomers are all compounds which have the same brief formula.
