AlBr3 is sold as a solution in CH2Br2. This is a rather exotic solvent and somewhat difficult to work with as well, because of its relatively high boiling point. CH2Cl2 is much more convenient to use in organic synthesis. Assuming AlBr3 is soluble in CH2Cl2, explain why selling it as a solution in that solvent might not be a good idea.
For reaction a+ b = c the colorless reactants produce deep red complex. Heating makes the color dissapear. Once cooled the deep red color retuns
Sketch a potential energy versus reaction coordinates diagram for the following reaction
Suppose a reaction has a standard Gibbs-free energy of 2.90 kJ/mol, calculate the relative ratio of product to reactant.
