The equation for the reaction of benzaldehyde (C7H6O) with methanol (CH4O) to give benzaldehyde dimethyl acetal (C9H12O2) and water is given below. A catalyst is also used in the reaction but does not affect the stoichiometry. C7H6O + 2 CH4O → C9H12O2 + H2O In a reaction, 10.0 g of benzaldehyde are mixed with 2.69 g of methanol. What is the theoretical yield of benzaldehyde dimethyl acetal in grams?
For this question, you can ignore part (5). (10 points each) 3.11. The Cannizzaro reaction is a disproportionation that takes place in strongly basic solution and converts aromatic aldchydes to the corresponding benzyl alcohol and sodium benzoate. Several mechanisms, all of which involve a hydride transfer as a key step, have been postulated. On the basis of the following information, formulate one or more mechanisms that would be consistent with all the data provided. Indicate the significance of each observation...
