Describe any important differences between benzopinacol and benzopinacolone in the IR, H NMR spectra.
Water/methanol and water/acetone are viable solvent systems for recrystallization, but water/chloroform and water/pentane are not
For the reaction:2CH4(g) C2H2(g) + 3H2(g) 0.115 mole of CH4 was placed in a 1.00 L container. At equilibrium it was found that the [C2H2] = 0.035 M. What is the value of the equilibrium constant?
