The reaction between chloroform (CHCl₃) and chlorine gas (Cl₂) proceeds by the following mechanism.
Cl₂ $\rightarrow$ 2 Cl
CHCl₃ + Cl $\rightarrow$ CCl₃ + HCl
CCl₃ + Cl $\rightarrow$ CCl₄
Which of the following substances are intermediates in the above mechanism?

Quizplus · Accepted Answer

Intermediates are species that are formed in one step of a reaction mechanism and consumed in another. Here, Cl (from the dissociation of Cl2) and CCl3 (formed from the reaction of CHCl3 with Cl) are both produced and then consumed in subsequent steps, making them intermediates.
