Question

The bond formed between iron (electronegativity = 1.9) and chlorine (electronegativity = 3.2) is

Answer 1

Here the chemical bond formed between iron and chlorine is an ionic bond, we can check this either through two ways, looking and identifying that Fe is a metal and Cl is a nonmetal, and thus would only allow for ionic bonds to be formed, I or by taking the difference in electronegativity and seeing if it is greater than or equal to 1.3. To be ionic.

Answer 2

Polar covalent.

Step-by-step explanation:

Hello,

In this case, ionic and covalent bonds could be differentiated by subtracting the constituents' electronegativities. Thus, for iron and chlorine, we have:

`\Delta E=E_(Cl)-E_(Fe)=3.2-1.9=1.3`

Hence, when such difference is less than 1.7, the bond is polar covalent as it is also greater than 0.7.

Best regards.
