Nomenclature of Alkanes Rule: 1) Find the longest carbon chain--name it. 2) Name substituents off the longest carbon chain. 3) Number longest carbon chain starting at the end closest to the first substituent (make sure first substituent gives lowest number). 4) Name alkane by first arranging all the substituents in alphabetical order (each preceded by the carbon number to which it is attached to, plus a hypen) and then name the alkane.

Example: Br Br trans-1,2-dibromocyclopropane Cl F cis-1-chloro-2-fluorocyclohexane (both substituents on axial position)...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
