Oxidation mechanism of benzoin to benzil?
Benzoin is oxidized to benzil through a two-step process involving an intermediate compound called benzilic acid. In the first step, benzoin undergoes oxidation to form benzilic acid by the action of a strong oxidizing agent like nitric acid. In the second step, benzilic acid decarboxylates to produce benzil, a dimer of benzaldehyde.
How can one determine the rate law from a given mechanism?
To determine the rate law from a given mechanism, you can use the slowest step in the reaction as the rate-determining step. The coefficients of the reactants in this step will give you the order of the reaction with respect to each reactant. This information can then be used to write the overall rate law for the reaction.
What does the rate determining step graph reveal about the reaction mechanism?
The rate determining step graph shows the slowest step in a reaction, which determines the overall rate of the reaction. This step often indicates the mechanism of the reaction, as it is typically the step with the highest activation energy.
What is the rate law that is consistent with the proposed mechanism?
The rate law that is consistent with the proposed mechanism is determined by the slowest step in the reaction, known as the rate-determining step. This step will dictate the overall rate of the reaction and the rate law will be based on the reactants involved in this step.
Why use KOH in benzilic acid rearrangement?
Potassium hydroxide (KOH) is used in the benzilic acid rearrangement as a base to deprotonate the α-carbon of the benzilic acid. This deprotonation step generates a carbanion intermediate, which then undergoes rearrangement to form the desired α-hydroxy acid product. KOH is a strong base that is effective in promoting this rearrangement reaction.
What do we call each step that makes up a reaction mechanism?
Each step in a reaction mechanism is referred to as an elementary step.

Why is a cycle of events in one step control or affect a previous step?
feedback mechanism
Is the transition state the slowest step in a reaction mechanism?
The transition state is not a step in a reaction mechanism; it is a high-energy state that exists at the peak of the reaction potential energy diagram. The slowest step in a reaction mechanism is often referred to as the rate-determining step, which has the highest activation energy and determines the overall rate of the reaction.
What is a feedback mechanism?
its a cycle of events in which information from one step controls or affects a previous step
What is a mechanical mechanism?
its a cycle of events in which information from one step controls or affects a previous step
What is the rate law that is consistent with the proposed mechanism?
The rate law that is consistent with the proposed mechanism is determined by the slowest step in the reaction, known as the rate-determining step. This step will dictate the overall rate of the reaction and the rate law will be based on the reactants involved in this step.
What is a cycle of event in which one step controls a previous?

What Specializes in rationalizing reactions?
A reaction mechanism is specialized in rationalizing reactions by proposing step-by-step sequences of molecular events that explain how reactants are transformed into products. This approach helps to understand the role of each species involved in the reaction and the factors influencing the reaction's outcome.
