WebJul 4, 2015 · Cyclopentane, on the other hand, is normally as an "envelope" which allows less close packing. Similarly, cyclohexane has very close cystalline packing which may account for its low melting point. Then, after its crystalline structure melts away, our intuition gives way to the boiling point expectancies. Again, this is not definite. WebJan 23, 2024 · There are 4 general groups of cycloalkanes: Small rings (cyclopropane, cyclobutane) Common rings (cyclopentane, cyclohexane, cycloheptane) Medium rings (from 8-12 membered) Large rings (13 membered and higher) Cycloalkanes can be substituted and named as cycloalkyl derivatives, and disubstituted cycloalkanes can be …
