Answer

1Chirality centers

Chirality centers are atoms in a molecule containing four non-identical groups and are non-superimposable mirror images. Molecules containing chiral centers are chiral compounds, but there is an exception of meso compounds containing a symmetry plane.

2An example of a compound with two chirality centers, R and S

(c) A compound with two chirality centers (R and S) is shown below. The upper carbon of the symmetry plane has an S configuration, and the lower carbon of the symmetry plane has an R configuration. This compound is also considered a meso compound.
