- B I
- C Cl
- D Br
Step-by-Step Verified Solution
_ Aryl chlorides and bromides can easily be prepared by electrophilic substitution of arenes (toluene)
with Cl 2 and Br 2 respectively in the presence of Lewis acid catalyst (Fe in dark).
_ Reaction with I 2 is reversible and requires the presence of oxidising agent.
_ Corresponding fluoroarene is not prepared by this method due to high reactivity of fluorine. Hence, �X� is F.
