Passage / Comprehension

Electronegativity is the property of a bonded atom. The relative tendency of an atom to attract the shared electron pair towards itself is called electronegativity. electron affinity electronegativity both measure the power of attracting electrons but electron affinity is concerned with an isolated gaseous atom while electronegativity is concerned with the atom in combination.

Which of the following relation is CORRECT according to Mulliken's Scale ?

Options:

Answer:

C

Solution:

Mulliken electronegativity ( $X_{M}$ ) is the average of ionization potential (I.P.) and electron affinity (E.A.). The Pauling scale ( $X_{P}$ ) relates to Mulliken's.

Mulliken's electronegativity ( $X_{M}$ ) is given by:

$X_{M} = \frac{I . P . + E . A .}{2}$

When I.P. and E.A. are in electron volts (eV), the conversion to the Pauling scale ( $X_{P}$ ) is:

$X_{P} = \frac{I . P . + E . A .}{5.6} = \frac{X _{M}}{2.8}$

Therefore, option C is correct.
