Question

What is the % ionic character in hi? Given electronegativity of h = 2.2 and i = 2.6?

Answer 1

Answer:

Linus Pauling proposed an empirical relationship which relates the percent ionic character in a bond to the electronegativity difference ΔχΔχ.

Percent ionic character =(1−e−(Δχ/2)2)×100=(1−e−(Δχ/2)2)×100

But I'd like to correct the definition of percent ionic character in your question using dipole moment μμ (not Observed value of ionic character):

Percent ionic character = μobservedμcalculatedμobservedμcalculated ×100%×100%

Where μcalculatedμcalculated is calculated assuming a 100% ionic bond.
