Question

A reaction occurs via the following sequence of elementary steps. What is the reaction intermediate?

Answer 1

Answer:

C is the reaction intermediate.

Explanation:

A reaction intermediate is a molecular structure that is formed during the reaction but then is converted in the final products.

Usually, these reaction intermediates are unestable and, for that reason, the lifetime of these structures is low.

In the reaction, you can see in the first step C is produced, but also, in the second step reacts producing D. As is produced and, immediately consumed,

C is the reaction intermediate.
