  • A monocycloalkane is a cycloalkane whose molecule contains only one ring.  The number of rings in a cyclic molecule is defined as the minimum number of bonds that must be broken in order to convert the molecule into an open-chain fragment.

    eg:  Cyclopentane

     

     

    The minimum number of bonds that must be broken in order to convert cyclopentane into an open-chain fragment is one, meaning the number of rings in cyclopentane is one.  Cyclopentane, therefore, is a monocycloalkane.

    Monocycloalkanes are by far the most common cycloalkanes.  Thus, the term cycloalkane is commonly used to mean monocycloalkane.
