About Bond Polarity
Bond polarity results from the unequal sharing of electrons between atoms with different electronegativities. The greater the electronegativity difference, the more polar the bond. This affects molecular properties like solubility, boiling point, and reactivity. Polar molecules dissolve in polar solvents (like water), while nonpolar molecules dissolve in nonpolar solvents.
