From monochlorination of (2R) - 2-bromobutane at C1 is formed (2S) - 2-bromo-1-chlorobutane.

From monochlorination of (2R) - 2-bromobutane at C4 is formed (2R) - 3-bromo-1-chlorobutane.

According to Cahn-Ingold-Prelog rules, the priority of halogen substituents decreases in the following sequence:

-I > - Br > - Cl > - F

According to the rule, chlorine has priority over bromine, so the configuration changes at C1 substitution.
