Question

Which of the following statements about monosaccharide structure is true?

A) Aldoses and ketoses differ in the position of their hydroxyl groups.
B) Monosaccharides can be classified according to the spatial arrangement of their atoms.
C) All monosaccharides contain carbon, hydrogen, oxygen, and nitrogen atoms.
D) A six-carbon sugar is called a pentose.

Answer 1

The correct answer is B.

Step-by-step explanation:

In stereoisomers, isomers differ in the orientation or spatial arrangement of their atoms.

The bonds of carbon atoms are three-dimensional geometry, their bonds can rotate in such a way that they offer a multitude of alternative positions. This allows the existence of the different stereoisomers of monosaccharides.

Have a nice day!
