The Hannay-Smith empirical equation relates the electronegativity difference () of two bonded atoms — Chemical Bonding Chemistry Question
Question
The Hannay-Smith empirical equation relates the electronegativity difference ($\Delta E.N.$) of two bonded atoms to the percentage ionic character of their covalent bond. Which is the correct mathematical expression?
Answer: A
💡 Solution & Explanation
The Hannay-Smith equation is empirically derived to estimate ionic character. It is strictly stated as $[16 (\Delta E.N.) + 3.5 (\Delta E.N.)^2] \%$, providing a rough approximation of bond polarity.
