Question

The ____ product is favored in reactions that are slow, reversible, at higher temperatures, and with a weaker, smaller base.

Answer

The thermodynamic product is favored in reactions that are slow, reversible, at higher temperatures, and with a weaker, smaller base.
The thermodynamic product is favored in reactions that are slow, reversible, at higher temperatures, and with a weaker,…
Note ↓: Path [1] occurs faster than Path [2] because it results in removal of the less hindered 2° hydrogen, forming an enolate on the less substituted α carbon. Path [2] results in removal of a 3° hydrogen, forming the more stable enolate with the more substituted double bond. This enolate predominates at equilibrium.

Through induction, oxygen pulls some of the electron density out of these α-Hydrogens bonded to Carbons, ____ them.

Oxygen pulling on C-H bonds with α-hydrogens, makes it relatively easy to ____ the α -carbon of an aldehyde or ketone.
