Scatter plot showing percent ionic character vs. electronegativity difference for various compounds.

Verified step by step guidance
1
Identify the electronegativity difference between Cl and F. The electronegativity of Cl is approximately 3.0 and for F it is approximately 4.0.
Calculate the electronegativity difference: |4.0 - 3.0| = 1.0.
Locate the value of 1.0 on the x-axis (Electronegativity Difference) of the provided graph.
Find the corresponding point on the y-axis (Percent Ionic Character) that aligns with the electronegativity difference of 1.0.
Estimate the percent ionic character of the ClF bond by reading the y-axis value at the point where the electronegativity difference is 1.0.
