What is the key difference between polar and nonpolar covalent bonds?
What is the key difference between polar and nonpolar covalent bonds?
- Polar covalent bonds have more electrons than nonpolar covalent bonds.
- Nonpolar covalent bonds have unequal sharing of electrons, while polar covalent bonds involve equal sharing.
- Polar covalent bonds involve unequal sharing of electrons, while nonpolar covalent bonds involve equal sharing. (correct)
- Nonpolar covalent bonds are stronger than polar covalent bonds.
Why do polar molecules have the strongest intermolecular forces?
Why do polar molecules have the strongest intermolecular forces?
- Since they lack partial charges.
- Because they have a balanced distribution of charges.
- Due to their symmetrical structure.
- They exhibit dipole-dipole interactions. (correct)
