Answer to Question 1


Answer to Question 2

4-Hydroxy-4-methyl-2-pentanone would result from an aldol reaction between two molecules of acetone. Ketones are less reactive electrophiles than aldehydes because of steric hindrance and inductive effects. In addition, there is a two-fold excess of aldehyde in this experiment so that very little of the aldol product from the reaction between two molecules of acetone is observed.
