Question 2 How are reactions between aldehydes and nucleophiles fundamentally different than reactions between acyl chlorides and nucleophiles? Aldehydes are readily oxidized by nucleophiles to carboxylic acids. Acyl chlorides have a leaving group, Cl¯, whereas aldehydes do not. Aldehydes do not form tetrahedral intermediates with nucleophiles. Acyl chlorides readily form enol tautomers. Question 3 Which one of the following does not react with benzoyl chloride, C 6 H 5 COCl ? NH 3 CH 3 NH 2 (CH 3 ) 2 NH (CH 3 ) 3 N Question 4 What is the product of the reaction sequence shown above? 2-methyl-1-pentanol
