- Arrange the compounds in order of decreasing basicity A. ethylamine B. 2-aminoethanol C. 3-amino-1-propanolarrow_forwardSynthetize 3-phenyl-2-propenoic acid from benzaldehyde using whatever organic/inorganic reagents are needed. 3-phenyl-2-propenoic = 3-phenylacrylic acidarrow_forwardChapter 1 (Carbonyl compounds I) Explain how the class I carbonyl compound reacts? What will be the product when ethylamine and propyl amine reacts with acetyl chloride? Why only one amide obtained after the reaction of acetyl chloride with a mixture of ethylamine and trimethylamine? Excess amine is required in the reaction of acetyl chloride with amine whereas excess alcohol is not required in the reaction of acetyl chloride and alcohol. Why? List the following ester in order of decreasing reactivities towards hydrolysis with reason: Methyl benzoate, p-nitro methyl benzoate and p-methoxy methyl benzoate The reaction of an ester with an amine is not as slow as the reaction of an ester with water or an alcohol. Explain with reason. Explain why the rate of aminolysis of an ester cannot be increased by H+, OH- or OR-. How can you activate the carboxylic acid? Is acid catalyzed hydrolysis of acetamide a reversible or an irreversible reaction. Explain. Chapter 2 (Carbonyl compounds II)…arrow_forward
