Question
Chapter 10, Problem 88CP
Interpretation Introduction
Interpretation:
The amount of heat released when 54.0 g of diborane is combusted should be calculated.
Concept Introduction:
Enthalpy of a reaction is a state function thus; change in enthalpy of a reaction does not depend on the path of the reaction.
The change in enthalpy is same if the same reaction takes place in one step or series of steps. This is known as Hess’s law. There are following characteristics of change in enthalpy which are important to calculate the change in enthalpy of a reaction using Hess’s law.
- For a reversed reaction, the sign of enthalpy change of the reaction also reversed.
- If any reactant or product is multiplied by any integer in the
chemical reaction , enthalpy change of that reactant or product is also multiplied by the same integer.

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:

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...]
