If x, y and z are electronegativity on Mulliken scale, ionisation potential (in V) and electron affinity (+, in eV) respectively, then the electron affinity in the terms of electronegativity and ionisation potential will be :

A

z=x+y2z = \frac{x + y}{2}

B

y=x+z2y = \frac{x + z}{2}

C

x=z−y2x = \frac{z - y}{2}

D

z = 2x – y

Answer

z = 2x – y

Explanation

Solution

According to Mulliken's, the electronegativity

= lonisationenergy+Electronaffinity2\frac{lonisationenergy + Electronaffinity}{2}
