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 balanced chemical equation for the formation of acetic anhydride from two acetic acid molecules is: 2 CH₃COOH → (CH₃CO)₂O + H₂O. The structure of acetic anhydride can be represented as follows: O || CH₃ - C - O - C - CH₃ || O

Step by step solution

01

1. Writing the balanced chemical equation for the formation of acetic anhydride from acetic acid molecules

Acetic acid has the molecular formula CH₃COOH. Since we are dealing with the condensation reaction, two molecules of acetic acid combine to form acetic anhydride and one molecule of water. The balanced chemical equation for the formation of acetic anhydride can be written as: 2 CH₃COOH → (CH₃CO)₂O + H₂O

2. Representing the structure of acetic anhydride

Now, let's represent the structure of acetic anhydride. Acetic anhydride consists of two acetyl groups (CH₃CO) bonded to an oxygen in between. The structure can be depicted as: O || CH₃ - C - O - C - CH₃ || O

Monosaccharides can be categorized in terms of the number of carbon atoms (pentoses have five carbons and hexoses have six carbons) and according to whether they contain an aldehyde (aldo- prefix, as in aldopentose) or ketone group (keto- prefix, as in ketopentose). Classify glucose and fructose in this way.
