Achemical bond is considered polar when the value of the electronegativity difference falls between__and__; nonpolar when the value is less

Answer;

0.5 and 1.6

0.5

A chemical bond is considered polar when the value of the electronegativity difference falls between 0.5 and 1.6 ; nonpolar when the value is less than 0.5.

Explanation;Nonpolar Covalent is a type of bond occurs when there is equal sharing  of the electrons in the bond. For example in molecules such as Cl2, H2 and F2.Polar Covalent is a type of bond occurs when there is unequal sharing between the two atoms, of the electrons in the bond. For examples in molecules such as; NH3 and H2O. If the electronegativity difference between the atoms involeved in bond formation is less than 0.5, then the bond is nonpolar covalent. While, If the electronegativity difference is between 0.5 and 1.6, then the bond is considered polar covalent But when the electronegativity difference is greater than 2.0, then the bond is ionic

The answer should be c.
