Given that ionization potential and electron gain enthalpy of chlorine are 13 eV and 4 eV respectively. The electronegativity of chlorine on Mulliken scale, approximately equals to

Options

  1. A8.5 eV
  2. B6 .0 eV
  3. C3 .0 eV
  4. D1 .5 eV

Correct answer

C. 3 .0 eV

Step-by-step solution

So according to the Mulliken's scale we have to calculate the electronegativity of chlorine when ionisation potential and electron gain enthalpy is given So we know the formula of electronegative χ   =   IP   +   EA 5 . 6 χ   =   13   +   4 5 . 6 χ   =   17 5 . 6 χ   = 3   eV
