to assign a name to enantiomers
step 1: is it stereocenter?
step 2: assign priority of atoms directly attacted to stereocenter ( if same then go to next atom of that molecule) look @ P.table the higher atomic number the higher the priority

step 4: draw arrows from 1,2,3
step 5: if arrows turn right then R if arrows turn left then S
