A linear polymer is built by joining 25 monomers through condensation reactions, with one water molecule released for each bond formed. How many water molecules are released?
A.25
B.24
C.26
D.50
Explanation
Core Concept
A linear chain of n monomers contains n−1 covalent links. Joining 25 monomers therefore requires 24 condensation events and releases 24 water molecules. The reasoning tests polymer accounting without requiring memorization of a particular carbohydrate's molecular structure.
Correct Answer
B24
