Detailed explanation-1: -The bond will either be non-polar or polar depending upon the specific electronegativity difference. Typically, an electronegativity difference of less than 0.5 will be a non-polar covalent bond, while polar covalent bonds are between those that have an electronegative difference of approximately 0.5-1.9.
Detailed explanation-2: -Although there are no hard and fast rules, the general rule is if the difference in electronegativities is less than about 0.4, the bond is considered nonpolar; if the difference is greater than 0.4, the bond is considered polar.
Detailed explanation-3: -An electronegativity difference of zero, of course, indicates a nonpolar covalent bond. Figure 4.9. 4 The electronegativity values derived by Pauling follow predictable periodic trends with the higher electronegativities toward the upper right of the periodic table. Fluorine has the highest value (4.0).
