Question

Using the empirical Hannay-Smith equation, calculate the percentage ionic character of a generic chemical bond between atoms $A$ and $B$, given that the electronegativity of $A$ is $1.0$ and the electronegativity of $B$ is $3.0$.

Answer: 46

💡 Solution & Explanation

The electronegativity difference is $\Delta E.N. = 3.0 - 1.0 = 2.0$. According to the Hannay-Smith equation, the percentage ionic character $= 16(\Delta E.N.) + 3.5(\Delta E.N.)^2$. Substituting the values: $16(2.0) + 3.5(2.0)^2 = 32 + 3.5(4) = 32 + 14 = 46\%$.
