Chapter 24, Problem 24.82(choose chapter or problem)
When each of the d-aldohexoses assumes an a-pyranose form, the CH2OH group occupies an equatorial position in the more stable chair conformation.

Explain this observation and then draw the more stable chair conformation of l-idose in its a-pyranose form.
