Chapter 24: Problem 54

Acetic anhydride is formed from two acetic acid molecules, in a condensation reaction that involves the removal of a molecule of water. Write the chemical equation for this process, and show the structure of acetic anhydride.

Short Answer

Expert verified
The chemical equation for the condensation reaction between two acetic acid molecules (CH3COOH) forming acetic anhydride ((CH3CO)2O) and water (H2O) is: 2 CH3COOH -> (CH3CO)2O + H2O The structure of acetic anhydride is: O O || || CH3-C-O-C-CH3

Step by step solution

01

1. Identify the structure of acetic acid

Acetic acid (CH3COOH) has the following structure: O || CH3-C-OH The carboxyl group (-COOH) is the functional group in acetic acid where the condensation reaction takes place.
02

2. Understand the condensation reaction

A condensation reaction is a reaction in which two molecules combine to form a larger molecule, with the elimination of a small molecule in the process, such as water or methanol. In this case, we have two acetic acid molecules reacting with one another to form acetic anhydride and a water molecule.
03

3. Write the chemical equation of the reaction

The chemical equation of the condensation reaction between two acetic acid molecules (CH3COOH) leading to the formation of acetic anhydride (CH3CO)2O and water (H2O) is: 2 CH3COOH -> (CH3CO)2O + H2O
04

4. Show the structure of acetic anhydride

During the condensation reaction, one hydrogen atom from the hydroxyl (-OH) group of one acetic acid molecule combines with the hydroxyl group (-OH) of the other acetic acid molecule to form water (H2O), leaving behind an acetic anhydride molecule. The structure of acetic anhydride is: O O || || CH3-C-O-C-CH3 In conclusion, the chemical equation for the formation of acetic anhydride from acetic acid molecules is: 2 CH3COOH -> (CH3CO)2O + H2O

Most popular questions from this chapter

Which statement best explains the chemical differences between DNA and RNA? (a) DNA has two different sugars in its sugar-phosphate backbone, but RNA only has one. (b) Thymine is one of the DNA bases, whereas RNA's corresponding base is thymine minus a methyl group. (c) The RNA sugar-phosphate backbone contains fewer oxygen atoms than DNA's backbone. (d) DNA forms double helices but RNA cannot.

(a) One test for the presence of an alkene is to add a small amount of bromine, which is a red-brown liquid, and look for the disappearance of the red-brown color. This test does not work for detecting the presence of an aromatic hydrocarbon. Explain. (b) Write a series of reactions leading to para-bromoethylbenzene, beginning with benzene and using other reagents as needed. What isomeric side products might also be formed?

(a) Are \(\alpha\) -glucose and \(\beta\) -glucose enantiomers? (b) Show the condensation of two glucose molecules to form a disaccharide with an \(\alpha\) linkage. (c) Repeat part (b) but with a \(\beta\) linkage.

Indicate whether each statement is true or false. (a) Pentane has a higher molar mass than hexane. (b) The longer the linear alkyl chain for straight- chain hydrocarbons, the higher the boiling point. (c) The local geometry around the alkyne group is linear. (d) Propane has two structural isomers.

True or false: The weaker a single bond in a molecule, the greater the chance it will be the site of a reaction (compared to stronger single bonds in the molecule).
