CycloalkanesCycloalkanes

Cycloalkanes are saturated hydrocarbons in a ring structure.They tend to have strong aromas.Smaller ring structures have stressed bonds that will require a spring, larger ring structures will not have stressed bonds and will not require a spring.They are named with the prefix cyclo-.
