A dehydration synthesis reaction between glucose (C₆H₁₂O₆)and fructose (C₆H₁₂O₆)produces a molecule of sucrose (C₁₂H₂₂O₁₁).Why don't the two individual molecular formulae add up to the same number of atoms in the sucrose product?
A)Oxygen must be burned/consumed during the reaction.
B)In a dehydration reaction,a water molecule (H2O)is removed from the final molecule formed.
C)In a dehydration reaction,a water molecule (H2O)is added to the final molecule formed.
D)Hydrogen must be burned/consumed during the reaction.

Question

Quizplus · Accepted Answer

Dehydration synthesis is a type of chemical reaction in which a water molecule is removed from two smaller molecules to form a larger molecule. In the case of glucose and fructose, a water molecule is removed from them to form sucrose. This means that the final molecule has fewer atoms than the sum of the atoms in the reactants. Therefore, the correct answer is B, as option B correctly describes the process of dehydration synthesis. Option A and D are incorrect because there is no combustion involved in dehydration synthesis, and no atoms are burned or consumed. Option C is also incorrect because a water molecule is removed, not added, in a dehydration synthesis reaction.
