Answer:
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 (<em>neither reactants nor products</em>).
- 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.
Change of appearance, change in size and shape of a substance, change in phase of a substance, and I'm pretty sure expansion/contraction is an answer, too.
