The Synthesis of isoxazoline derivatives are done by reacting with suitable chalcone and treated with hydroxylamine hydrochloride. The spectral determination was confirmed by using spectroscopic technique i.e. IR, NMR and Mass. Further study has been done by used photophysical property, viscometric measurement, and their thermodynamics parameters Entropy, Enthalpy and Gibbs free energy. The study shows positive value of ΔS, negative value of ΔG and positive value of ΔH which confirms that the reaction is endothermic and spontaneous. The maximum absorption of synthesized derivative 3-(4’ methyl phenyl)-5-(furan) isoxazoline was found at 311 nm. The data obtained have been also observed that viscosity of solution increases with increase in the concentration of solution and positive value of B-coefficient may attribute to strong solute-solvent interaction. On the other hand value of A-coefficient is almost negative which indicates weak solute-solute interaction.
