Multiple Choice

In the context of organic chemistry reactions, why are there fewer intermediates than reactants?

Intermediates are only formed in endothermic reactions.

Intermediates are less stable and quickly convert to products.

Intermediates are formed in smaller quantities due to limited reactant availability.

Intermediates are consumed by side reactions, reducing their number.

Verified step by step guidance

Understand the role of intermediates in a chemical reaction: Intermediates are species that are formed during the conversion of reactants to products. They are not present in the initial reactants or the final products but are crucial for the reaction pathway.

Consider the stability of intermediates: Intermediates are often less stable than both reactants and products. This instability means they tend to convert quickly into more stable products, reducing their presence in the reaction mixture.

Analyze the reaction conditions: In many reactions, intermediates are formed in smaller quantities because the conditions favor the rapid conversion to products. This can be due to factors like temperature, pressure, or the presence of catalysts.

Evaluate the availability of reactants: The formation of intermediates is dependent on the availability of reactants. If reactants are limited, fewer intermediates can be formed, which in turn limits their concentration in the reaction mixture.

Consider side reactions: Intermediates can also be consumed by side reactions, which are alternative pathways that do not lead to the desired product. This consumption further reduces the number of intermediates present in the reaction.
