Questions & Answers

Q: What is the chair conformation in glucopyranose?

The chair conformation is the stable form of a six-membered ring in glucopyranose, where axial and equatorial positions are present. It ensures stability and allows for efficient attachment of functional groups.

Q: How many axial and equatorial positions are there in the chair conformation of glucopyranose?

In the chair conformation of glucopyranose, there are six axial positions and six equatorial positions. These positions play a crucial role in determining the stability and reactivity of the molecule.

Q: Can chain conformation be applied to other monosaccharides?

Yes, the concept of chain conformation can be applied to other monosaccharides. It refers to the arrangement of atoms and functional groups in a way that ensures stability and optimal reactivity.

Q: How does the configuration of functional groups affect the chair conformation of monosaccharides?

The configuration of functional groups, such as the presence of OH groups at axial or equatorial positions, determines whether the monosaccharide adopts the alpha or beta form. This configuration plays a significant role in the chair conformation and overall stability of the molecule.

Summary & Key Takeaways

• Glucopyranose, a six-membered ring, is stable when it adopts the chair conformation.

• In the chair conformation, there are six axial (upward) positions and six equatorial (sideways) positions.

• Chain conformation can also be applied to other monosaccharides, such as alpha and beta forms of de ellos.
