Swapping two substituents always inverts the configuration (eg. S -> R), so doing one swap, followed by a second swap gets back to the original configuration (eg. S -> R -> S). So, rather than rotating like I did in (2), you could draw out the chiral centre with 1, 2, 3, 4, then do two sequential swaps that end up putting the lowest priority group going away from you (ie. with the hashed bond). | |

If yes, Do I only need to consider the molecules which I gave the priority (1,2,3,4) when doing molecule swap method to determine the R and S configuration of the above compound(4th priority on the plane of the paper)? | |
