| Abstract | ||
| Abstract The interaction of 2, 3-butadione monooxime (B) with phenol and its five substituents in n-heptane are studied by using uv spectroscopy. The study lead to the formation of mono-protonated, bi-protonated as well as intramolecular hydrogen bonding species. The later are found to be of the type O − H∙∙∙∙N and O − H∙∙∙∙O. The process of hydrogen bond formation is confirmed here from uv spectra and the calculated thermodynamic parameters. This shows that ∆H and ∆S have a negative signs, in addition to their values which support hydrogen bond formation. | ||
