When two monosaccharides undergo a dehydration synthesis reaction in which type of molecule is formed?

A disaccharide is formed

Explanation:

A disaccharide is a sugar that is formed when two monosaccharides undergo a dehydration reaction. The two monosaccharides (also known as monomers), are joined together by a glycosidic bond. This bond joins two OH groups together to produce an oxygen bonding them, and forming water as a product (the reason it is called a dehydration reaction is because water is being "removed" from the molecule).
