The synthesis of imines and enamines typically occurs under mildly acidic conditions, yet the reaction that you will perform in this experiment is successful without the need of such acid. Why
Are the methyl groups enantiotopic or diastereotopic in the ketone? How about the alcohol?
Suppose that 1.10 mg of gold is obtained in a colloidal dispersion in which the gold particles are spherical, with a radius of 1.00 * 10^2 nm. (The density of gold is 19.3 g/cm^3.) What is the total surface area of the particles?
The reaction is spontaneous at all temperatures C) It is impossible to determine if the reaction is spontaneous without calculations D) The reaction will only be spontaneous at low temperatures E) The reaction will only be spontaneous at high temp
Calculate the pH of 0.10 M KOH where KOH is a strong base. The answer should be above 7 since its a BASE.
