The answer is C): Iodine and chlorine are close in electronegativity, so they would form covalent bond with each other. Chorine is more electronegative, thus it would pool electron density from iodide to itself gaining partial negative charge. Therefore, it would be polar covalent bond with partial negative charges on chlorine atom Solution The answer is C): Iodine and chlorine are close in electronegativity, so they would form covalent bond with each other.
