WebSep 21, 2024 · It turns out that there is a flagpole interaction between the H atoms on C 1 and C 4 that causes steric strain. If we look closer, however, we can also see an electronic argument that speaks to its higher energy. If we look down the C 2-C 3 or C 6-C 5 bonds, we see that all of the bonds are eclipsed. WebOther than that, the two hydrogen atoms on C1 and C4 are very close to each other and cause steric strain. This is also called the “flagpole” interaction of the boat conformation. The two types of strains make the boat conformation have considerably higher energy (about 30 kJ/mol) than the chair conformation.
