What is the rate of reaction with Cl_(2), Br_(2) and I_(2) with CH_(2)

1.	What is the rate of reaction with Cl_(2), Br_(2) and I_(2) with CH_(2) -= CH_(2).
Answer» Solution :Reactivity order `Cl_(2) gt Br_(2) gtI_(2)`. Rate of REACTION of ALKYNE with iodine `(I_(2))` is so SLOW hence special condition is required to ARRANGE EQUILIBIRUM.
