Textbook Question
Chapter 12.3, Problem 12.1.1PE
Consider the two-dimensional square lattice of Figure 12.4. The “packing effiency” for a two-dimensional structure would be the area of the unit cell, times 100%. What is the packing efficiency for a square lattice for atoms of radius a/2 that are centered at the lattice points?
a. 3.14%
b. 15.7%
c. 31.8%
d. 74.0%
e. 74.0%

It is not unexpected that the methoxyl substituent on a cyclohexane ring
prefers to adopt the equatorial conformation.

What is unexpected is that the closely related 2-methoxytetrahydropyran
prefers the axial conformation:
H
H
OMe
OMe
A Gp=-0.6 kcal/mol
Methoxy: CH3O group
Please be specific and clearly write the reason why this is observed. This effect that provides
stabilization of the axial OCH 3 group in this molecule is called the anomeric effect. [Recall in the way of
example, the staggered conformer of ethane is more stable than eclipsed owing to bonding MO
interacting with anti-bonding MO...]
