Exemplar Problems

Problem 9 : Discuss the factors that affect bond polarity. Provide examples of molecules with polar and nonpolar bonds.

Solution :

Factors affecting bond polarity include the electronegativity difference between bonded atoms and molecular geometry. Molecules with a significant electronegativity difference between atoms tend to have polar bonds. For example, HCl has a polar covalent bond, while H₂ has a nonpolar covalent bond.
