Given that ionization potential and electron gain enthalpy of chlorine are and respectively. The electronegativity of chlorine on Mulliken scale, approximately equals to
Solution
On Mulliken scale, E.N. \(=\frac{\mathrm{I} \cdot \mathrm{E}+\mathrm{E} . \mathrm{A}}{2}=\frac{13+4}{2}=8.5 \mathrm{eV}\)
Mulliken values are nearly 2.8 time larger than Pauling value
So, on Pauling scale \(=\frac{8.5}{2.8}=3 \mathrm{eV}\)
So, correct answer is 8.5 eV according to Mulliken scale.
