Question 44 Hydrolysis of an acid anhydride yields ONLY carboxylic acids. True False
True or false: a) The electron-withdrawing substituents do not impact the acidity of carboxylic acids. b) Hydrolysis of nitriles is a method to synthesize carboxylic acid. c) The order of reactivity of carboxylic acid derivatives is as follow: Acyl chloride > Acid anhydride > Ester > Amide. d) SOCl2, PCl3 and PCl5 are three types of special reagents to convert carboxylic acid to acyl chloride. e) Acyl chlorides are the most reactive common acyl derivatives, and can be used to...
Questions 12-20 are true and false! (12) Hydrolysis of nitriles is a method to synthesize carboxylic acid. (13) The order of reactivity of carboxylic acid derivatives is as follow: Acyl chloride > Acid anhydride > Ester > Amide. (14) SOCI2, PC13 and PCls are three types of special reagents to convert carboxylic acid to acyl chloride (15) Acyl chlorides are the most reactive common acyl derivatives, and can be used to synthesize anhydride, ester, and amide. (16) Acyl chloride is...
What hydrolysis products are formed when the wax is treated with aqueous sulfuric acid? Carboxylic Acids + Alcohol
An acid anhydride reacts with an alcohol to form one ester and one carboxylic acid. An unsymmetrical acid anhydride can react with alcohol at either carbonyl carbon, so there are two possible esters and two possible carboxylic acids. Draw the structures of all possible organic products formed in the following reaction. Do not draw counterions or byproducts. CH3 OH CH3 НАС CH3 CH3 HO So
Which of the following carboxylic acid derivatives is the least reactive in a hydrolysis reaction? Amide Anhydride Ester Acid halide

2. Acid hydrolysis of amides one of the most used methods in the synthetic transformation of amides to carboxylic acids. Provide a stepwise mechanism of the transformation below. НаО, Н* NH2 "ОН
Carboxylic acid esters can undergo acid catalyzed hydrolysis, neutral hydrolysis and base catalyzed hydrolysis. Below is a table with three structurally related carboxylic acid esters and the second order reaction rate constants for the acid-catalyzed mechanism (k_A) and the rate constant for the base-catalyzed mechanism (k_B). The difference between the three compounds is mainly the substitution of hydrogen atoms on R_1 with the more electronegative chlorine atoms. a) Explain why there is only a small change in k_A for the...
