A Kinetic Study of the Effect of Hydrogen Bonding of Acid catalysed hydrolysis of Iso-propyl Methenoate in Aquo- Ethanol Solvent Systems

The effect of hydrogen ondings existing in the reaction media has been highlighted by studying the acid catalysed solvolysis of iso- propyl methanoate in aquo-ethanol solvent systems. The depletion and enhancement observed respectively in iso-composition and iso- dielectric activation energies reveal that the transition state is solvated and initial state is desolvated with addition of ethanol in the reaction media. Almost unity value of the slope of the plots of log k values against log [H+] values shows that the reaction follows AAC2 mechanism. From, the values of iso-kinetic temperature, which comes to be 284.17, it is inferred that in aquo-EtOH reaction media, the reaction follows Barclay- Butler rule and there is weak but acceptable interaction between solvent and solute in aquo-EtOH (aquo-ethanol) reaction media.
