What makes a cycloalkane different from other alkanes?
Non benzenoid cyclic compounds are called alicyclic compounds or cycloalkanes.
Cycloalkanes are actually alkanes arranged in ring form instead of a normal straight or branched chain as in regular alkanes.
Note that cycloalkanes always have 2 carbon atoms less than its aliphatic straight chain counterpart.
Following are the first four cycloalkanes.
Cycloalkanes, however, like regular alkanes are essentially non polar in nature and have low melting and boiling points.
