Assertion: Among halogens fluorine is the best oxidant
Oxidants - Oxidants are also known as oxidising agents.
These are those species which oxidise others and get reduced by tjemselves .
Thus, more is the tendency of species to get reduced, stronger will be its oxidising power.
Reason: Fluorine is the most electronegative atom.
Fluorine belongs to 17th group, Electronic configuration of Fluorine is −1s2 2s2 2p5
Thus, fluorine needs only one electron to achieve stable inert gas configuration and has very small size. Hence, fluorine is the most electronegative atom.
The given assertion is correct and given reason is also correct. But reason is not the correct explanation of assertion.

Assertion(A): Among halogens fluorine is the best oxidant.
Reason(R): Fluorine is the most electronegative atom.
The correct answer is option B: Both A and R are true and R is not the correct explanation of A.
Explanation:
Assertion:
Fluorine is the best oxidant among halogens. An oxidant is a substance that accepts electrons from another substance during a chemical reaction. Fluorine has a high tendency to gain one electron to achieve a stable electron configuration, making it a strong oxidant.
Reason:
Fluorine is the most electronegative atom. Electronegativity is the measure of an atom's ability to attract electrons towards itself in a chemical bond. Fluorine has the highest electronegativity value among all the elements, indicating its strong ability to attract electrons. This high electronegativity makes fluorine highly reactive and a strong oxidant.
Explanation of the Correct Answer:
Both the assertion and reason are true. Fluorine is indeed the best oxidant among halogens due to its high tendency to gain electrons. Additionally, fluorine is the most electronegative atom, which explains its strong oxidizing power. However, the reason provided does not directly explain why fluorine is the best oxidant among halogens. Other factors such as atomic size and electron shielding also play a role in determining the oxidizing power of halogens. Therefore, the reason is not the correct explanation of the assertion.
In conclusion, fluorine's high electronegativity and strong tendency to gain electrons make it the best oxidant among halogens. However, its status as the best oxidant cannot be solely attributed to its electronegativity.
