WebIt contains both of the larger atoms (Cl) equatorial, and they are cis as desired. However, in Fig 10, the two axial groups on carbons # 1 and 2 (the two H that are shown) are both pointing up. This is impossible. In a valid chair, the axial groups alternate up/down as one goes around the ring; see Figure 2B, above. Web11 de ene. de 2024 · To convert it to a chair, we start by drawing in a chair template ( foot-rest on right) with ring oxygen at back-right and number each carbon. We then assign “up and down” to each of the substituents on the Haworth and map those on to our chair template: The last step is to clean it up by making the hydrogens implicit, if desired. coburns abita springs la https://automotiveconsultantsinc.com
