Answer:
25%
Explanation:
A way to estimate the ionic character of a bond between two atoms is using the formula:
Where χ₁ is the electronegativity of the more electronegative atom of the bond, while χ₂ is the other atom's electronegativity.
In the case of this problem χ₁ is the electronegativity of F and χ₂ is Chlorine's.
So the estimate is:
