Understanding Polar and Nonpolar Compounds
Polar and nonpolar compounds differ primarily in their electric charge distribution. These differences significantly affect their chemical properties, interactions, and solubility.
Polar compounds possess regions with partial positive and negative charges due to an unequal sharing of electrons between atoms. This uneven electron distribution leads to dipole moments.
Nonpolar compounds have equal sharing of electrons, resulting in no distinct positive or negative poles. This occurs either due to symmetrical molecular geometry or identical electronegativity between atoms.

FAQs on Difference Between Polar and Nonpolar Compounds
1. What is the main difference between polar and nonpolar?
Polar compounds have unequal electron sharing, creating partial charges, whereas nonpolar compounds have equal electron sharing without partial charges.
2. What is the difference between a polar and nonpolar solvent with examples?
Polar solvents (water, ethanol) dissolve polar substances; nonpolar solvents (benzene, hexane) dissolve nonpolar substances.
3. Is H₂O polar or nonpolar?
H₂O (water) is polar due to its bent shape and uneven electron distribution.
4. How to know if polar or nonpolar?
Check the electronegativity difference and molecular shape; asymmetry and electronegativity differences indicate polarity.
5. What are three nonpolar solvents?
Hexane, benzene, and carbon tetrachloride (CCl₄) are nonpolar solvents.
6. Is oil polar or nonpolar?
Oil is nonpolar, hence unmixable with water.
7. Is NaCl polar or nonpolar?
NaCl (table salt) is ionic, not polar or nonpolar, but dissolves readily in polar solvents like water.
8. Is CO₂ polar or nonpolar?
CO₂ is nonpolar due to its linear, symmetrical structure.
9. What is polar and non-polar?
Polar compounds have partial charges and unequal electron distribution, while nonpolar compounds have no partial charges and symmetrical electron distribution.
10. Why is water a good solvent?
Water is a good solvent because of its polarity, allowing it to dissolve many ionic and polar substances.
