Chapter 7, Problem 7.45P
Interpretation Introduction

Interpretation:

Using the appropriate bond energies, ΔHrxn0 for the given reaction is to be estimated. The more stable form that is imine or enamine is to be determined.

Concept introduction:

Aldehydes and ketones can exist in two forms, i.e., keto-enol form. In the enol form, the species has a carbon atom that is simultaneously a part of a C = C bond, characteristic of an alkene and is bonded to OH, characteristic of an alcohol. In the keto form, the hydrogen atom attached to carbon atom that is adjacent to the C = O group, called alpha hydrogen. In a keto-enol tautomerization, the keto form is in equilibrium with its enol form via proton transfer steps. The imines can also exhibit this type of tautomerization. By calculating the energy of the molecule or the enthalpy of the reaction using bond energies, the stability of particular form (keto or enol) can be determined. The molecule having more enthalpy of reaction is more stable.

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
