Vaughn Yu · Answer 1

The intermediates in this reaction are Cl and CCl₃.

Explanation:

To indicate the intermediate in this reaction, we should firstly define the intermediate. The intermediate is the species that produced within the steps of the reaction and consumed in the later step/s and does not appear in the overall reaction (neither reactants nor products). The mechanism of the reaction contains 3 steps: Cl₂ ↔ 2Cl Cl + CHCl₃ → HCl + CCl₃ Cl + CCl₃ → CCl₄ The overall reaction is: Cl₂ + CHCl₃ → HCl + CCl₄ So, the intermediates in this reaction are Cl and CCl₃. Thus, 2 moles of Cl is produced in the first step and consumed in the second and third steps. 1 mole of CCl₃ is produced in the second step and consumed in the third step.
