The electron affinities of halogens are ...

The electron affinities of halogens are `F=322, Cl=349,Be=324,I=295kJ mol^(-1)`. The higher value for `Cl` as compared to that of `F` is due to

A

Weaker electron-electron repulsion in Cl

B

Higher atomic radius of F

C

Higher atomic radius of F

D

More vacant p-subshell in Cl

Text Solution

Verified by Experts

The correct Answer is:
A
Due to high electronegativity value and small size of F , its not easy to add the electron as compared to the Cl . Cl is less electronegative and large in size as compare to the F hence addition of `e^(-)` takes place easily. Therefore high electron affinity value.

The amount of energy released when an electron is added to an isolated gaseous atom to produce a monovalent anion is called electron affinity of first electron affinity or electron gain enthalpy. The first electron affinity is given a negative sign as the addition of an electron to a neutral atom is an exoergic process. The addition of electron to A^(-) requires energy to overcome the force of repulsion. Thus, the second electron affinity is an endoergic process. The magnitude of electron affinity depends on a number of factors such as (i) atomic size (ii) effective nuclear charge (iii) screening effects (iv) half and fully filled orbitals and (v) shape of orbital. In general, electron affinity increase as the atomic radii decrease in a period. However, there are exceptions when the atoms have stable configuration. In a group, electron affinity decreases as the size increases. However, the members of 3rd period have somewhat higher values than the members in the 2nd period of the same subgroups. The electron affinities of halogens are: F =- 332, CI =- 349, Br =- 324,I =- 295 kJ mol^(-1) The higher value of CI as compared to that of F^(-) is due to:
