Explanation:
Detailed explanation-1: -The monosaccharides can be divided into groups based on the number of carbon atoms in the molecules, thus: trioses have 3-C atoms, tetroses have 4-C atoms, pentoses have 5-C atoms, and hexoses have 6-C atoms.
Detailed explanation-2: -Cyclic structures of this kind are termed furanose (five-membered) or pyranose (six-membered), reflecting the ring size relationship to the common heterocyclic compounds furan and pyran shown on the right.
Detailed explanation-3: -Glucose is six membered ring, while fructose is a five-membered ring.
Detailed explanation-4: -Furan is a five-membered cyclic compound with one oxygen and four carbon atoms.
