Question

what type of bond formation occurs when two monosaccharides join to form a disaccharide? dehydration synthesis covalent bond hydrogen bond ionic bond

Explanation:

When two monosaccharides form a disaccharide, a dehydration synthesis reaction occurs. In this process, a water molecule is removed, and a covalent bond (specifically a glycosidic bond, which is a type of covalent bond) is formed. But the key process here is dehydration synthesis as the mechanism of bond formation between the monosaccharides to make a disaccharide involves removing a water molecule (dehydration) and synthesizing the bond. Covalent, hydrogen, and ionic bonds are types of bonds, but the process of forming the bond between monosaccharides to disaccharide is dehydration synthesis.

Answer:

A. Dehydration synthesis
