Question

Reaction intermediates are formed during the reaction but are not shown in the overall reaction are important to a multistep reaction.
Which of the following statements about intermediates is true?

• A. Intermediates can be formed and held at that state indefinitely due to the stable nature of the intermediate species.
• B. Intermediates are sometimes formed in simple, one-step reaction mechanisms.
• C. An intermediate is formed in one step of a multistep mechanism then used completely in a subsequent elementary step.
• D. An intermediate formed in a biological system is very different in function than one formed in a non-biological system.

Answer 1

The correct option is A Intermediates can be formed and held at that state indefinitely due to the stable nature of the intermediate species.

A reaction intermediate or an intermediate is a molecular entity that is formed from the reactants (or preceding intermediates) and reacts further to give the directly observed products of a chemical reaction. Most chemical reactions are stepwise, that is they take more than one elementary step to complete.

$A$ is correct answer the Intermediates can be formed and held at that state indefinitely due to the stable nature of the intermediate species.
