Key Concepts

Electronegativity

Electronegativity is a measure of an atom's ability to attract and hold electrons within a bond. The greater the difference in electronegativity between two bonded atoms, the more uneven the electron distribution and the more polar the bond becomes.

Bond Polarity

Bond polarity arises from the unequal sharing of electrons between atoms in a covalent bond due to differences in electronegativity. A polar bond develops when one atom attracts the shared electrons more strongly, resulting in a partial negative charge on that atom and a corresponding partial positive charge on the other.

Partial Charges

Partial charges, denoted as ?+ and ?-, indicate the distribution of electron density within a polar bond. The atom with the greater electronegativity obtains a partial negative charge (?-), while the less electronegative atom acquires a partial positive charge (?+). This concept is crucial for understanding the behavior of polar bonds and predicting molecular interactions.
