Most polar binding: KCl<\/strong>
Least polar binding: Cl\u2082<\/strong><\/p>\n\n\n\n
Polarity of a bond depends on the difference in electronegativity between the atoms involved. A greater difference results in a more polar bond, and a smaller or zero difference results in a less polar or non-polar bond.<\/p>\n\n\n\n
KCl has the most polar bond among the given molecules. Potassium (K) is a metal with very low electronegativity, and chlorine (Cl) is a nonmetal with high electronegativity. The electronegativity difference between K (0.82) and Cl (3.16) is about 2.34. This large difference causes a significant transfer of electrons from K to Cl, making the bond highly ionic and polar. K loses one electron to become K\u207a, and Cl gains one to become Cl\u207b. This electron transfer forms a strong electrostatic attraction, characteristic of a polar ionic bond.<\/p>\n\n\n\n
Cl\u2082 is a diatomic molecule made of two identical chlorine atoms. Since both atoms have the same electronegativity (3.16), the electron pair in the bond is shared equally. This results in a nonpolar covalent bond, where there is no separation of charge across the molecule. Therefore, Cl\u2082 has the least polar or zero polarity among the options.<\/p>\n\n\n\n
NaI (Sodium Iodide)<\/strong> and LiBr (Lithium Bromide)<\/strong> are also ionic compounds like KCl, but their electronegativity differences are slightly smaller. Na (0.93) and I (2.66) differ by 1.73, while Li (0.98) and Br (2.96) differ by 1.98. These values are less than the K\u2013Cl difference, so their bonds are slightly less polar than KCl, but more polar than covalent Cl\u2082.<\/p>\n\n\n\n
