WebThe structure of cyclooctatetraene is In regular octagone the internal angles are135 But in this case each carbon issp2hybridised hence the bond angle should be120The bond … WebWhy Cyclooctatetraene is not planar whereas its Dianion is a planer molecule? The reason for this lack of planarity is that a regular octagon has internal angles of 135 degrees, while sp2 angles are most stable at 120 degrees. To avoid the strain the molecule therefore adopts a nonplanar geometry.

WebScience. Chemistry. Chemistry questions and answers. 10. (10pts) The Huckel energies for cyclooctatetraene (assuming it is planar) are given below. Determine the resonance stabilization energy by comparing it to 4 ethene molecules. EG Q - 2B E a - 1.418 ET E3, E4 a, 0 (nonbonding) E2 a +1.418 E a + 2B. Early studies demonstrated that COT did not display the chemistry of an aromatic compound. Then, early electron diffraction experiments concluded that the C-C bond distances were identical. However, X-ray diffraction data from H. S. Kaufman demonstrated cyclooctatetraene to adopt several conformations and to contain two distinct C–C bond distances. This result indicated that CO… rotary lift dealer

WebOct 16, 2009 · according to KBB page 369, this molecule (1 3 5 7-cyclooctatetraene) is anti-aromatic. i thought that's correct, because it has 8 pi electrons and all carbons are sp2, therefore planar... but i remember in topscore or something, they said this thing isn't planar and therefore isn't anti-aromatic nor aromatic. is topscore wrong? WebJun 24, 2015 · If cyclooctatetraene were planar, it would be an antiaromatic compound according to Hückel's rule, because it has 8 π-electrons. However, since its lowest energy conformation is non-planar, cyclooctatetraene can also be considered a non-aromatic … WebJan 23, 2024 · Furthermore, cyclooctatetraene has 8 π-electrons, a number not consistent with the Hückel Rule.
