WebMay 9, 2024 · $\begingroup$ If you draw the methyl group attached to the cyclohexane with a dash, then either a) you do not know (e.g., lack of experimental evidence), or b) you do not want to assign the configuration of the carbon atom of the cyclohexane binding to the methyl group (e.g., because it is irrelevant for the discussion, or you know it is ... WebCompounds that are optically inactive as they are achiral. Compounds that had the plane of symmetry is a special category called mesocompound. Which has chiral centre but the molecules itself are achiral. The 2^n is a general rule to estimate the number of stereoisomer, it won't help in the case of mesocompound. 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). palmdale community foundation
