Having completed this tutorial you should be able to :

describe the changes in energy as the conformations of molecules such as alkanes change through staggered, eclipsed, gauche or anti forms by rotation about a C-C bond.

recognize and indicate the presence of chiral centres in a range of organic molecules.

extend the use of nomenclature of organic molecules presented so far in the course to now include the ranking of groups around a chiral centre and the assignment of R- or S- configurations to the structure.
