Cyclohexane log p
WebThe structures of cyclohexane-1,3-dione analogues and the respective values of p I 50 (−log I 50) were used as input data. Structures were aligned using the option “bondType_atomNum” in order that the maximal subgraph required equivalent bond types and atom numbers to match and that the number of conformers was 50 using the MM3 … Cyclohexane is a cycloalkane with the molecular formula C6H12. Cyclohexane is non-polar. Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products (in which it is sometimes used). Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to nylon. Cyclohexyl (C6H11) is the alkyl substituent of cyclohexane and is abbreviated Cy.

WebSep 24, 2024 · Conformations of Cyclohexane. A planar structure for cyclohexane is clearly improbable. The bond angles would necessarily be 120º, 10.5º larger than the ideal tetrahedral angle. Also, every carbon-hydrogen bond in such a structure would be eclipsed. The resulting angle and eclipsing strains would severely destabilize this structure. WebApr 10, 2024 · ASK AN EXPERT.
