WebJul 18, 2024 · The chiral Pt NPs have an onset potential of 0.92 V at −0.1 mA⋅cm −2 (Fig. 3C), which is modestly higher (30 mV) than that found for the commercial Pt/C and significantly higher (80 mV) than the achiral Pt NPs. Moreover, chiral Pt NPs also exhibit a higher half-wave potential (0.87 V) than that of achiral NPs (0.80 V) and Pt/C (0.84 V). 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).

WebA molecule's chirality can be determined by several overlapping conditions. Here are two examples of molecules with differing chirality, achiral and chiral.
