Question
Chapter 12, Problem 12.5P
Interpretation Introduction
Interpretation: The reason as to why heats of hydrogenation cannot be used to determine the relative stability of
Concept introduction: Hydrogenation reaction is exothermic in nature due to the fact that the bonds are stronger in product than in reactant. Heat of hydrogenation can be used as measure for relative stability of

Br
Write the answer below.
Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H
atoms that would contribute to the same signal as the H already highlighted red.
Note for advanced students: In this question, any multiplet is counted as one signal.
Number of signals in the 'H NMR spectrum.
For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to
the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in top
molecule
For the molecule in the bottom drawing area, highlight in red any other H atoms that will
contribute to the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in bottom
molecule
In the drawing area below, draw the major products of this organic reaction:
1. NaOH
?
2. CH3Br
If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area
instead.
No reaction.
