Expert Solution

Step 1

Given molecule:

Step 2

The systematic naming of organic compound is given by IUPAC. The naming of organic compound is done such that the structure of organic compound is correctly interpreted from the name.

The configuration of a chiral center is designated using R and S configuration.

If the priority order goes from 1-2-3-4 in clockwise direction then the configuration is R.

If the priority order goes from 1-2-3-4 in anticlockwise direction then the configuration is S.
