Glucose (C₆H₁₂O₆)has a single carbonyl group (-C=O)in its linear form.Based on the number of oxygen atoms in glucose,how many hydroxyl groups (-OH)would you expect glucose to have?
A)6
B)5
C)3
D)1

Question

Quizplus · Accepted Answer

Glucose has six carbon atoms, and each carbon atom is bonded to either a hydrogen atom or a hydroxyl group (-OH). The carbonyl group (-C=O) is also bonded to a single oxygen atom. Therefore, the total number of oxygen atoms in glucose is 6 (from the hydroxyl groups) + 1 (from the carbonyl group) = 7. Since each hydroxyl group contains one oxygen atom, the number of hydroxyl groups in glucose is 7 - 1 = 6. Therefore, the correct choice is B) 5, as glucose actually contains five hydroxyl groups (-OH).
