Question

f2 is most reactive of all the four common halogen explain.

Answer 1

Due to small size and electronegativity

Answer 2

Hey !!

F₂ is most reactive of all the four common halogens (F₂ , Cl₂ , Br₂ and I₂) because of the following reasons :

1. F₂ has the lowest bond dissociation enthalpy.
2. The bonds formed between F and most of the elements are much stronger than those formed by other halogens.
3. F₂ has the highest electrode potential ( + 2.87 V ) of the four halogens, therefore, F₂ is the strongest oxidising agent and hence can be reduced more readily as compared to Cl₂ , Br₂ and I₂

GOOD LUCK !!
