This assignment is worth a total of 40 raw points. 1. (10 points) When a cyanohydrin is exposed to aqueous base, a hydrolysis reaction occurs which yields an aldehyde or ketone as the major organic product. An example of such a hydrolysis reaction is shown below. Assume that H 2 O is the solvent in this reaction. C C H 3 C OH N OH H 2 O C CH 3 O + C N In the space below, propose a mechanism for this reaction. Use curved arrows to show movement of electron pairs, and be sure to draw the structures of all important reaction intermediates. Be sure to show all lone pairs and nonzero formal charges explicitly in all structures that you draw! If an intermediate is a resonance hybrid, it is only necessary to draw the MOST IMPORTANT contributing resonance structure. Points will be deducted if you draw only a relatively less important contributing resonance structure!
