Identify molecular formula of laevulose .
- A \(\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6\)
- B \(\mathrm{C}_5 \mathrm{H}_{10} \mathrm{O}_5\)
- C \(\mathrm{C}_4 \mathrm{H}_8 \mathrm{O}_4\)
- D \(\mathrm{C}_3 \mathrm{H}_6 \mathrm{O}_3\)
Answer & Solution
Correct Answer
(A) \(\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6\)
Step-by-step Solution
Detailed explanation
Fructose \(\left(\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6\right)\) is a laevorotatory ketohexose and it shows laevorotation.
\([\propto]_D^{20}=-92.4^{\circ}\)
Thus, fructose is also called laevulose.
\([\propto]_D^{20}=-92.4^{\circ}\)
Thus, fructose is also called laevulose.
