Chalcones can be easily oxidized in presence of oxalic acid, by Cr(VI) in acetic acid medium, the rate of cooxidation was found to be a fractional order with respect to the chalcones and its substituents. The order with respect to the chromic acid is unity whereas order with respect to oxalic acid is also a fractional order. The effect of various p...

... According to mechanism of reaction , it is showed that presence of cage effect and solvation effect which are effecting to the absorption peaks directly . These factors basically depend on nature of material and solvent used to solve the material , so this leads to combine solvent molecules round the reacted material which can be explained as surrounding for obstical the molecules to interact with each other , which can be noticed in case of decreasing the absorptivity , changing charge for dissimilar of ions that can positively and negatively effecting to the stability of formed compounds [20] . In conclusion we can say that the solvent has great effect m which can explain the contrast in the values of absorption , exclusively in polar solvents as aversely to ability of the compound to interaction with polar solvents because they have functional groups like carbonyl one and that is because of cage effect . ...
Iodoform oxidation for drug ketone (spusforonion) at room temperature by using the conductivity study and spectrophotometric in basic medium. The conductivity study showed that molar conductance values were decreased with increasing of time at (2x10-4-4x10-4) concentration, while at ( 5x10-4-6x10-4) the value of molar conductance was increased, due to the reaction in presence of basic medium and apply the Helmy's theory of oxidation solutions was applied in ethanol for the initial infinity Molaric conductivity Ʌοat 250 ̊was found the linear relationship between the lnɅ and C1/2for the weak electrodes. The second study was spectrophotometric in a basic medium which showed that the reaction is related to the first order for the oxidation drug concentration by the iodoform.
