Step 1

To determine the more polar bond, we need to compare the difference in electronegativity values between the atoms involved in each bond. The greater the difference, the more polar the bond. For O-Cl: Electronegativity of O = 3.5, Electronegativity of Cl = 3.0, Show more…

Key Concepts

Electronegativity

Electronegativity is a chemical property that describes the ability of an atom to attract electrons toward itself when it forms a chemical bond. The concept is essential in predicting bond polarity as differences in electronegativity between two bonded atoms lead to an unequal sharing of electrons.

Bond Polarity

Bond polarity arises when there is a significant difference in electronegativity between two atoms in a bond. This difference creates partial positive and negative charges at either end of the bond, influencing physical properties such as solubility, melting and boiling points, and reactivity.
