WebThe Cahn-Ingold-Prelog system is a set of rules for assigning R and S (absolute configurations) to chiral centers. The idea is to assign each of the 4 atoms attached to a chiral center a priority, 1 through 4, based primarily on atomic number. Once the priorities are assigned the spacial arrangement of these 4 atoms will be in one of two ... WebWhen determining R or S, the lowest priority substituent needs to be facing towards the back, which can be done "turning" the molecule at the chirality center that the hydrogen is attached too.

I am trying to figure out the configuration for this chiral carbon to answer a homework question, however they arbitrarily include a "D" group as shown in the image. My guess is that it is some higher priority group than the carbon, and lower priority than the halide, making the configuration (S). Is this correct?
