Understand the concept of chemical bonds: Chemical bonds are forces that hold atoms together in compounds. They can be classified into different types based on how electrons are shared or transferred between atoms.
Learn about covalent bonds: Covalent bonds involve the sharing of electrons between atoms. These can be further divided into polar and nonpolar covalent bonds based on the equality of electron sharing.
Define polar covalent bonds: A polar covalent bond occurs when electrons are shared unequally between two atoms. This happens because one atom has a higher electronegativity, attracting the shared electrons more strongly.
Contrast with nonpolar covalent bonds: In nonpolar covalent bonds, electrons are shared equally between atoms, typically because the atoms have similar electronegativities.
Identify the correct bond type: Given the options, the bond resulting from unequal sharing of electrons is a polar covalent bond, as it involves partial charges due to the unequal distribution of electron density.
