Question
**Question:**

Which direction does the equilibrium below favor and what is the deciding factor?

**Chemical Reaction:**

On the left side:
- Structure with a ketone group attached to an amide (N–H).

Between the reactants and products:
- Arrow indicating reaction direction.
- Catalyst: H+ cat.

On the right side:
- Structure with an ester group.
- Amine group (NH₂).

**Answer Options:**

- ( ) reactants, electronegativity
- (●) reactants, resonance
- ( ) products, electronegativity
- ( ) products, resonance

**Explanation:**

The question asks about the favored direction of a chemical equilibrium and the deciding factor. The chemical structures show the transformation of an amide group into an ester and an amine. The correct answer, marked here, is "reactants, resonance," suggesting that resonance stabilizes the reactants more, favoring the reverse reaction direction.

Expert Solution
Step 1

In the given chemical reaction the amide reacts with alcohol in the presence of an acid catalyst to form an ester. The direction of equilibrium depends on the stability of the carboxylic acid derivative.
