WebThe atoms attached to C5 are C, H, H. There is no difference. To decide between C2 and C5, we must go one atom further out. From C2, C3 has F, C, H. From C5, C4 has C, H, H. C2 is therefore #2, and C5 is #3. If you assign these priorities to the groups, the sequence 1 → 2 → 3 goes in a counterclockwise direction (S). WebSep 9, 2024 · Locate the chiral or stereogenic center. Assign priority to each group based on the atomic number of the atom attached to the center, where 1 = high and 4 = low. Determine the direction of priority for the other three groups, in order of high to low priority (1 to 3). If the order is clockwise, then the center is R.
