Based on electronegativities,which of the following would you expect to be most ionic? A)N₂ B)CaF₂ C)CO₂ D)CH₄ E)CF₄

Question

Quizplus · Accepted Answer

To determine which compound is most ionic, we need to look at the difference in electronegativity between the two elements in each compound. The greater the difference, the more ionic the bond.
Using electronegativity values from the periodic table:
Ca = 1.00
F = 3.98
∆EN = |3.98 – 1.00| = 2.98
This is the greatest electronegativity difference among the options. Therefore, CaF2 is the most ionic compound.
