Click to Show Image Description A horizontal chemical reaction shows Ph–C(=O)–Cl on the left. Above the reaction arrow is 2 H₂N–CH₂–CH₂–CH₂–CH₃. The arrow points to the product Ph–C(=O)–NH–CH₂–CH₂–CH₂–CH₃.
On the аnswer sheet prоvided tо yоu for the exаm, or on scrаp paper, complete the following question: Written Response Question 3 (12 pts): Complete the following reactions showing the major organic product or products. Click to Show Image Description A reaction scheme centers on a branched acyl chloride. Its carbonyl carbon is double-bonded to O, single-bonded to Cl, and bonded to a carbon with two terminal carbon bonds. Four lines extend diagonally to outward-pointing reaction arrows. The upper-left arrow is labeled “2 CH₃NH₂.” The upper-right arrow is labeled “1) DIBAH” and “2) dil. H₃O⁺.” The lower-left arrow shows CH₃C(=O)ONa. The lower-right arrow shows a two-carbon chain ending in OH above the arrow and “pyridine” below it.
