Write the C.I.P (Cahn, Ingold, Prelog) nomenclature (nomenclature in R,S) of the following substances and find the isomers:
The first three:
R-bromochlorofluoromethane
The last:

The first three are superimposable, (= same substance which is enantiomer of the last !).
Many authors write (R) and (S) instead of R and S
