Question

If the electronegativity difference between two atoms is $0.7$ Pauling units, what is the bond type that will form between the atoms?

• A. Non-polar covalent
• B. Ionic
• C. Dispersion (London)
• D. Polar Covalent

Answer 1

The correct option is D Polar Covalent

If the difference is less than $0.4$, the bond is considered nonpolar covalent; between $0.4$ and $1.7$ is polar covalent, and above $1.7$ is ionic.

Thus If the electronegativity difference between two atoms is $0.7$ Pauling units, the bond type that will form between the atoms is Polar Covalent.
