Suppose that you have 1.55grams of nitroglycerin( also known as nitroglycerine, trinitroglycerin, trinitroglycerine) in a 603.0 mili litres of steel container at 20 degree celsius and one atm pressure.
Suppose we doubled the volume of the solution (by adding more solvent) while keeping the quantities of the reactants constant in a SN1 reaction.
However, if you treat formaldehyde (CH2O) with potassium cyanide in water, you will not produce the cyanohydrin. You may even produce C3H6O3 (i.e., dihydroxyacetone and glyceraldehyde). Explain this either in words or reactions.
