What type of linkage is formed when an alcohol and an acid react?
Correct answer: D. Ester linkage
- A. Ionic bond
- B. Peptide bond
- C. Glycosidic linkage
- D. Ester linkage
Explanation
Option D is correct. When an alcohol and an acid react, they undergo an esterification reaction to form an ester bond or linkage. This is a type of covalent bond formed between the hydroxyl group of the alcohol and the carboxyl group of the acid, resulting in the production of an ester and water. This reaction is distinct from other types of linkages such as ionic bonds, which involve electron transfer, peptide bonds, which occur between amino acids, and glycosidic linkages, which form between sugars.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
