Textbook Question
Chapter 7, Problem 36P
Explain the following observations: When tert-butyl bromide is treated with sodium methoxide in a mixture of methanol and water, the rate of formation of tert-butyl alcohol and tert-butyl methyl ether does not change appreciably as the concentration of sodium methoxide is increased. However, increasing the concentration of sodium methoxide causes a marked increase in the rate at which tert-butyl bromide disappears from the mixture.

we know that ethers, such as diethyl ether and tetrahydrofuran, are quite resistant to the action of dilute acids and require hot concentrated HI or HBr for cleavage. However, acetals in which two ether groups are linked to the same carbon undergo hydrolysis readily, even in dilute aqueous acid. How do you account for this marked difference in chemical reactivity toward dilute aqueous acid between ethers and acetals?
Propanal and propanone react in a similar way with acidified aqueous potassium cyanide, KCN. For this reaction to occur reasonably quickly, the pH of the solution should be approximately 4.
The reaction of propanal proceeds with acidified potassium cyanide proceeds more rapidly than that of propanone. Referring to the mechanism of the reactions, explain this phenomenon.
Propanal and propanone react in a similar way with acidified aqueous potassium cyanide, KCN. For this reaction to occur reasonably quickly, the pH of the solution should be approximately 4.
Draw a diagram to show the mechanism of the reaction of either propanal or propanone with acidified potassium cyanide.
