Neco 2023 Chemistry Question 41
Practice objective / multiple choice question 41 from the 2023 Neco Chemistry examination.
The electronegativities of sodium (Na) and chlorine (Cl) are \(0.93\) and \(3.16\) respectively. Using the formula \(\%\text{ ionic} = \bigl(1 - e^{-0.25(\Delta EN)^2}\bigr) \times 100\), where \(\Delta EN\) is the difference in electronegativity, determine the percent ionic character of the NaCl bond, rounded to the nearest whole number, and state the type of bond (ionic, polar covalent or non‑polar covalent) based on the \(\Delta EN\) value.
