General guidance
The concept used to solve this problem is to locate the anomeric carbon in the given structure and then name the compound using the configuration.
If the given monosaccharide, –OH group and 
group are trans to each other, then it is called as 
anomer. Similarly, if –OH group and group are cis to each other, then it is called as 
anomer.
If the group is drawn up, then it is known as D-sugar. If the group is drawn down, then it is known as L-sugar.
Anomers are the two structural forms of same molecule which differentiate from each other only in the direction of the OH (hydroxyl) group present at the hemiacetal carbon.
Six-membered ring containing an oxygen atom is known as pyranose ring. Similarly, the five-membered ring containing an oxygen atom is known as furanose ring.
Step-by-step
Step 1 of 3
The structure is as follows:
This is a six-membered ring, so it is a pyranose.
The name of the monosaccharide is 
.
Here, the –OH group and group are cis to each other, so it is a anomer. The is facing towards up, so it is D. Thus, the name of the monosaccharide is .
Step 2 of 3
The structure is as follows:
This is a six-membered ring, so it is a pyranose.
The name of the monosaccharide is 
.
Here, the –OH group and group are cis to each other, so it is a anomer. The is facing towards down, so it is L. Thus, the name of the monosaccharide is.
Step 3 of 3
The structure is as follows:
This is a five-membered ring, so it is a furanose.
The name of the monosaccharide is 
.
Here, the –OH group and group are cis to each other, so it is a anomer. The is facing towards up, so it is D. Thus, the name of the monosaccharide is.
