Enthalpy of formation propanone

WebAcetone oxime (acetoxime) is the organic compound with the formula (CH 3) 2 CNOH. It is the simplest example of a ketoxime. It is a white crystalline solid that is soluble in water, ethanol, ether, chloroform, and ligroin. It is used as a reagent in organic synthesis. WebNow do the calculation: Hess's Law says that the enthalpy changes on the two routes are the same. That means that: ΔH - 3267 = 6 (-394) + 3 (-286) Rearranging and solving: ΔH = 3267 + 6 (-394) + 3 (-286) ΔH = +45 kJ mol -1. Note: If you have a good memory, you might remember that I gave a figure of +49 kJ mol -1 for the standard enthalpy ...
