Final answer:
The major product of the reaction CH₃CClI is dichloromethane (CH₂Cl₂). This reaction involves a substitution reaction with another chlorine atom.
Step-by-step explanation:
The major product of the reaction CH₃CClI is dichloromethane (CH₂Cl₂).
In this reaction, CH₃CClI undergoes a substitution reaction with another chlorine atom, resulting in the replacement of the iodine atom with a chlorine atom.
This reaction can be represented as follows: CH₃CClI + Cl₂ → CH₂Cl₂ + CCl₃I
