The molecular formula for glucose is C₆H₁₂O₆.What would be the molecular formula for a polymer made by linking 10 glucose molecules together by dehydration reactions?

Question

Quizplus · Accepted Answer

When 10 glucose molecules (each with the formula C6H12O6) are linked together by dehydration reactions to form a polymer, 9 water molecules (H2O) are removed. This means the total formula for the polymer would be the sum of the components of 10 glucose molecules minus the components of 9 water molecules. The correct calculation leads to the formula C60H102O51, which corresponds to choice B when considering the subtraction of 18 hydrogen atoms and 9 oxygen atoms from the total present in 10 glucose molecules.
