Textbook Question
Chapter 16, Problem 92QRT
The standard molar entropy of methanol vapor, CH3OH(g), is 239.8 J K−1 mol-1.
- (a) Calculate the entropy change for the vaporization of 1 mol methanol (use data from Table 16.1 or Appendix J).
- (b) Calculate the enthalpy of vaporization of methanol, assuming that ΔrS° doesn’t depend on temperature and taking the boiling point of methanol to be 64.6°C.

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:

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...]
