The order of decreasing power as an oxidizing agent is
Correct answer: B. F₂>Cl₂>Br₂>I₂
- A. F₂>Br₂>Cl₂>I₂
- B. F₂>Cl₂>Br₂>I₂
- C. F₂<Cl₂<Br₂<I₂
- D. F₂<Br₂<Cl₂<I₂
Explanation
Oxidizing power refers to the ability of a substance to gain electrons and oxidize another substance. The oxidizing power of halogens decreases down the group. Fluorine (F₂) is the strongest oxidizing agent among the halogens, followed by chlorine (Cl₂), bromine (Br₂), and iodine (I₂).

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
