2 CEM 3331, Spring 2008 Exam 3, page 1 of 5 Extra Credit (5 pts) ow are reactions between aldehydes and nucleophiles fundamentally different than reactions between acyl chlorides and nucleophiles? Concept Test on 4/16/08 A. Aldehydes are readily oxidized by nucleophiles to carboxylic acids. B. Acyl chlorides have a leaving group, Cl, whereas aldehydes do not. C. Aldehydes do not form tetrahedral intermediates with nucleophiles. D. Acyl chlorides readily form enol tautomers. 1. (6 pts) ne or more of the following names do not follow the IUPAC rules. Circle the incorrect name(s) and provide a correct IUPAC name. A. 2-(2-isopropoxy-2-oxoethyl)cyclopentanone isopropyl 2-(2-oxocyclopentyl)acetate B. 5-formyl-3-hydroxy-2-methylpentanoic acid correct C. Edward Scissorhands 3-cyclopentyl-3-(1-propylbutyl)pentanedioic acid 2. (5 pts) Rank the following in terms of increasing acidity (1 = most acidic, 5 = least acidic) omework 9, Problem 1 F F
3 CEM 3331, Spring 2008 Exam 3, page 2 of 5 3. (9 pts) Acrolein reacts with sodium azide in aqueous acetic acid to form a compound (C ) in 71% yield. Propanal, when subjected to the same reaction conditions, is recovered unchanged. In the box below, suggest a structure for the product formed from acrolein. In the circle below, draw propanal. Give a brief explanation for the difference in reactivity between acrolein and propanal. 3 a 3 C 3 C(aq) acrolein Book Problem propanal Weak nucleophiles, such as the azide ion, add to an α,β-unsaturated aldehyde by conjugate addition. The resulting β-substituted aldehyde still has a strong C- double bond. Conversely, a weak nucleophile adds to an otherwise saturated aldehyde by addition at the carbonyl carbon to make a tetrahedral carbon. In the case of propanal (and most other aldehydes and ketones) the tetrahedral intermediate is less stable than the carbonyl compound and the equilibrium lies on the side of the aldehyde. 4. (10 pts) Fill in the product(s) of the following reaction and, using arrows to show the flow of electrons, propose a mechanism for the transformation. excess
