Remember the reactivity of halogens decreases down the group, therefore the addition reaction of alkenes with chlorine takes place faster with chlorine than for bromine with iodine being the slowest. Fluorine is the most reactive of all non-metals elements and does not produce a useful reaction with alkenes.

iodine is less reactive as compared to chlorine and hence it does not react with Ethane in the presence of light.
Explanation:
- For the halogen the reactivity gradually decreases as we move down the group. iodine lies below chlorine and fluorine in the modern periodic table and as a result of this the reactivity of iodine is less as compared to that of chlorine and fluorine.
- Now chlorine reacts with Ethane in the presence of Sunlight for ultraviolet rays.
- However iodine being less reactive as compared to chlorine does not react with it and even in the presence of Sunlight or ultraviolet rays.
