Abstract: | The interaction of p-nitrophenol with several electron-donors has been studied in aprotic and protic solvents by electronic absorption spectroscopy. The equilibrium data for different kinds of equilibria in 1,2-dichloroethane, n-butanol and acetonitrile have been obtained and discussed. The strong hydrogen bonding interaction between p-nitrophenol and a variety of electron donors has been investigated in heptane by electronic absorption spectroscopy. The interesting correlations obtained in terms of Mulliken's charge transfer model have been examined and extended in many cases. |
