What are the chiral centers of the molecule of nicotine?
Santiago AlfonsoThere's only one, and it's S.
The highest to lowest priority is (1,2,3,4):
- tertiary amine (highest atomic number here;
#-"NC"_2# ) - aromatic
#sp^2# (taken similar to tert-butyl, i.e.#-"CC"_3# ) - methylene (
#-"CH"_2# ) - hydride (
#-"H"# )You get that from going clockwise and crossing the hydride, but since the hydride is facing forwards rather than backwards, the configuration is the reverse of R, which is S.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
