The electronegativity difference between elements in a compound can be used to determine the type of bond present. The electronegativity values are typically measured on the Pauling scale.
Given that the electronegativity difference is 2.1, we can refer to the general guidelines for bond type:
If the electronegativity difference is less than 0.5, it is considered a nonpolar covalent bond.
If the electronegativity difference is between 0.5 and 1.7, it is considered a polar covalent bond.
If the electronegativity difference is 1.7 or greater, it is considered an ionic bond.
In this case, with a difference of 2.1, the bond is indicative of an ionic character. Therefore, the correct answer is:
c. fluorine
