Fluorine (F2) has the maximum E0 value (+2.87 V) among the halogens, hence, it reduces first than other halogens and acts as the best oxidant. Fluorine is the most electronegative atom due to its small size.

Hence, both assertion and reason are correct but reason is not the correct explanation for assertion.

Assertion (A) : Among halogens fluorine is the best oxidant.
Reason (R) : Fluorine is the most electronegative atom.
The correct option is (B) Both A and R are true but R is not the correct explanation of A.
Explanation:
Assertion (A): Among halogens fluorine is the best oxidant.
Reason (R): Fluorine is the most electronegative atom.
Explanation for Assertion (A):
Oxidation is a chemical process in which an atom or ion loses electrons. The ability of an element to accept electrons from another species during a chemical reaction is known as its oxidizing power or oxidizing strength. Among the halogens, fluorine is the most powerful oxidizing agent. This is because fluorine has the highest electronegativity among all the elements in the periodic table. Electronegativity is the tendency of an atom to attract electrons towards itself in a chemical bond. Fluorine has a high electron affinity and a strong attraction for electrons, making it a strong oxidizing agent.
Explanation for Reason (R):
Fluorine is the most electronegative atom in the periodic table. Electronegativity increases across a period from left to right and decreases down a group in the periodic table. Fluorine has the highest electronegativity value of 3.98 on the Pauling scale, indicating its strong pull on electrons. This high electronegativity is due to its small atomic size and high effective nuclear charge. The small size of fluorine allows it to have a strong attraction for electrons, making it highly electronegative.
Explanation for the Correct Option:
Both the assertion and the reason are true. Fluorine is indeed the best oxidant among halogens, and it is also the most electronegative atom. However, the reason provided does not directly explain why fluorine is the best oxidant among halogens. While high electronegativity contributes to the oxidizing power of an element, there are other factors such as electron affinity and ionization energy that also play a role in determining the oxidizing power. Therefore, the reason is not the correct explanation of the assertion.
In conclusion, fluorine is the best oxidant among halogens due to its high electronegativity, but the reason provided does not fully explain why fluorine is the best oxidant.
Reason (R) : Fluorine is the most electronegative atom.
The correct option is (B) Both A and R are true but R is not the correct explanation of A.
