Question

Assertion and reason type question.
Assertion(A): F is more electronegative than CI.
Reason (R): F has higher electron affinity than Cl.​

Answer 1

Answer:

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.

Answer 2

Answer:

A is correct and R is false

Explanation:

F is more electronegative but has lower electron affinity than Cl because of its smaller size.
