The value of electronegativity of atoms A and B are 1.20 and 4.0 respectively. The percentage of ionic character of bond is:
View answer and explanation
Correct option: D
Option D (72.24 %) is correct because the percentage of ionic character can be estimated using the Pauling equation: % ionic character = (1 - exp(-0.25 * (ΔEN)2)) * 100, where ΔEN is the electronegativity difference.
