For bromine the IE/EA ratio =10 / 3, Electronegativity of bromine is 2.8 on Mulliken's scale, its EA in kJ / mol will be . (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

IE =10 x ; EA =3 x According to Mulliken's scale XM=(I E+E A/544) 2.8=(10 x+3 x/544) ∴ x =(2.8 × 544/13)=117 kJ EA =3 x =117 × 3=351
