954 CHAPTER 20 • THE CHEMISTRY OF CARBOXYLIC ACIDS versus about 1.42 Å). The reason for this difference is that the C LO bond in an acid is an sp2–sp 3single bond, whereas the CLO bond in an alcohol or ether is an sp –sp3 single bond. The carboxylic acids of lower molecular mass are high-boiling liquids with acrid, piercing
