Question

the difference between a nonpolar covalent bond, a polar covalent bond, and an ionic bond.

Choose the BEST answer:

A.Ionic bonds can be considered as 100% polarized toward the metal.

B.Polar covalent bonds display partial polarization toward the nonmetal, while ionic bonds exhibit full polarization.

C.Nonpolar covalent bonds involve full/equal sharing of electrons, while polar covalent and ionic do not.

D.These three types of bonds are part of a continuum that is affected the average electronegativity of the bonded atoms.

Answer 1

The correct best option is

D. These three types of bonds are part of a continuum that is affected the average electronegativity of the bonded atoms.

statment C is also correct but it cannnot distinguish between Polar covalent and ionic bond

Covalent bonds are fomed between two non metals of same electronegativity. The electronegativity difference is 0-0.4 for non polar covalent bonds.

Polar covalent bonds is formed betweennon metals that have different electronegativities, resulting in unequal sharing of electrons The electronegativity difference between two non metals should be in range 0.5-1.9

Ionic bond has electronegativity difference of greater than 1.9 and it involves metal.
