Question

Arrange the non metals iodine fluorine bromine chlorine in decreasing order of their reacivity

Answer 1

Reactivity increases down the group despite a decrease in electronegativity. This is due to the very high bond enthalpy of Fluorine which decreases down the group, allowing reactions to occur more easily.

= Iodine --> Bromine --> Chlorine --> Fluorine

Answer 2

1) Fluorin

2)Chlorin

3)bromine

4)iodine

IN DECREASING ORDER.
