How many atoms are there in pyranose ring?
Correct answer: B. 6
- A. 5
- B. 6
- C. 3
- D. 7
Explanation
The correct answer is 6. A pyranose ring is a six-membered structure in organic chemistry, consisting of five carbon atoms and one oxygen atom. This configuration forms a stable ring, which is a common feature in carbohydrates such as glucose. Options A, C, and D are incorrect because they do not accurately represent the number of atoms in a pyranose ring.
