In initial steps of the sol-gel process, a reactive metal is treated with an alcohol to form a metal alkoxide. The metal alkoxide is then combined with water to form the metal hydroxide. The metal hydroxide is not formed directly by reaction of the metal with water because A the metal hydroxide formed in the two-step process is more soluble and is more easily utilized (B the alcohol stabilizes the metal hydroxide making it less susceptible to attack by the base added late the direct reaction of a reactive metal with water will give a complex mixture of metal oxides and hydroxide D finer particles are obtained in the two-step process E) the two-step process prevents oxidation of the metal to an unstable oxidation state

Suppose you took your two compounds, dissolved them in tertbutyl methyl ether and then added them to a separatory funnel. Now suppose you add in aqueous sodium bicarbonate and vigorusly shake the contents of the separatory funnel. ethanol will be dissolved in tert butyl methyl ether ether and valeric acid will be dissolved in the aqueous sodium bicarbonate layer. Draw the EXACT chemical structure that will exist in each of the layers after shaking with sodium bicarbonate. (Is it neutral or charged?)
