A compound with this many double bonds is typically described as adopting a “tub-like” conformation. A compound with this many total bonds previously used as a dry cleaning agent is used to induce liver damage in animal models. That compound is the simplest perfluorocarbon. In octahedral complexes, this is the lowest number for which there is a distinction between high-spin and low-spin states. A cyclic diene with this many carbon atoms is unstable because it spontaneously dimerizes via a pericyclic reaction. A ring with this many members is formed in the transition state for the Wittig reaction and for olefin metathesis. This is the number of ligands in Zeise’s salt and cisplatin as well as the number of bonds in a seesaw geometry. For 10 points, give this number of carbon atoms in butane. ■END■
