Provide a complete mechanism for the formation of 1,4-di-t-butylbenzene from t-butyl benzene, AlCl3, and t-butyl chloride. provide all resonance and intermediates. why is para preferred over meta and ortho
A 50/50 blend of engine coolant and water (by volume) is usually used in an automobile\'s engine cooling system. If your car\'s cooling system holds 5.80 gallons, what is the boiling point of the solution? Make the following assumptions in your ca..
For some enzyme reactions (for example, the hydrolysis of cAMP by phosphodiesterase in vertebrate retinal cones)the enzyme is present in large quantities,so that e0/s0 is not a small number.Fortunately,there is an alternate derivation of the Micha..
