Gce Model Questions Vol1 2020 Chemistry Question 41
Practice objective / multiple choice question 41 from the 2020 Gce Model Questions Vol1 Chemistry examination.
The electronegativities of sodium and chlorine are 0.93 and 3.16 respectively. Using Pauling's empirical formula for percent ionic character, \( \%\text{ionic}=\left(1-e^{-0.25(\Delta\chi)^2}\right)\times100 \), where \(\Delta\chi\) is the difference in electronegativity, calculate the percent ionic character of the Na-Cl bond and state whether the bond is best described as ionic, polar covalent or non‑polar covalent. (Round the percentage to one decimal place.)
