Question 6

In a covalent bond, how do the electronegativity of the participating atoms, bond polarity, and bond strength relate?

Accepted Answer

The greater the electronegativity difference, the more polar and weaker the bond.

Answer

Electronegativity has no impact on bond polarity or bond strength.

Answer

The greater the electronegativity difference, the less polar and stronger the bond.

Answer

Electronegativity only affects bond strength, not polarity.
