Question

D-Fructose is the sweetest monosaccharide. How does the Fischer projection of D-fructose differ from that of D-glucose? Match the words in the left column to the appropriate blanks in the sentences on the right.

1. ketone
2. carbon 3
3. carbon 2
4. carbon 1
5. an aldehyde
6. carbon 4
A. In D-glucose, there is______functional group, and the carbonyl group is at_____when looking at the Fischer projection.
B. In D-glucose, there is______functional group, and the carbonyl group is at______when looking at the Fischer projection.

Answer 1

5

4

1

3

Step-by-step explanation:

In D-glucose, there is an aldehyde functional group, and the carbonyl group is at carbon 1 when looking at the Fischer projection.

In D-Fructose, there is a ketone functional group, and the carbonyl group is at carbon 2 when looking at the Fischer projection.

Both of your questions say "glucose" so I gave you my answer to the best of my understanding which required me to change the second answer to FRUCTOSE.
