Question

Assertion: F is more electronegative than $Cl$.
Reason: F has high electron affinity than $Cl$.

• A. If both assertion and reason are true and the reason is a correct explanation of the assertion
• B. If both assertion and reason are true but reason is not a correct explanation of the assertion
• C. If the assertion is true but reason is false
• D. If both the assertion and reason are false
• E. If the assertion is false but the reason is true

Answer 1

Answer: (C)

If the assertion is true but reason is false

Here assertion is true but reason is false. F is more electronegative than chlorine, in fact it is most electronegative element of the periodic table but its electron affinity, the tendency to accommodate electrons, is less than the $Cl$ due to non availability of $d$-electrons.
