Cycloalkanes in Hydrogen-1 NMR

  1. May 12, 2016 #1
    Will members of the cycloalkane homologous series only ever show one peak in Hydrogen - 1 NMR spectroscopy due to the symmetry in the molecules?

    I can be wrong, but I believe it depends on how precise your measurements are. Boat and chair have different symmetries, so I wouldn't be surprised to see more than one peak even for cyclohexane.

    This will also be a question of temperature, whether the interconversion of the conformers is faster or slower than the NMR timescale.
