Chapter 4.12, Problem 30CC

Interpretation Introduction

Interpretation:

The axial 5-hydroxy-1,3dioxane is more stable than equatorial position should be explained.

Concept Introduction:

Conformational isomers:

• The two or more compounds have same molecular formula and different structural formulas are called conformational isomers.
• The Cyclohexane have a chair and boat conformations.
• The chair conformations of Cyclohexane have a axial and equatorial positions.
• The atom or group is occupy at similar to a vertical axis passing through the chair conformation of Cyclohexane ring is called axial position.
• The atom or group is occupy at similar to horizontal axis passing through the chair conformation of ring is called equatorial position.
• The substitution present in the equatorial position is more stable than axial because of 1,3-diaxial interactions are less in equatorial position.

Intramolecular hydrogen bonding:

• The bond between the electronegative atom and bonded hydrogen present in the same compound is called is called intramolecular hydrogen bonding.
