Polar
Polarity is when an entity contains two distinct and opposite poles that can either attract or repel each other
Polarity refers to the distribution of electrical charge over the atoms joined by a bond. When electrons in a molecule are not shared equally
Why Does Polar Occur
Electronegativity is the tendency of an atom to attract shared electrons.
The larger the difference, the more polar the bond.
Types Of Polarity
Bond Polarity
Molecular Polarity
Bond Polarity
A single covalent bond between two atoms with different electronegativities becomes polar.
The more electronegative atom pulls electrons closer, developing a partial negative charge (δ–).
Molecular Polarity
Even if a molecule has polar bonds, it might be non-polar overall depending on its geometry
A molecule is polar if the dipoles do not cancel each other.
How does molecular polarity influence the solubility of substances in water?
In what way does polarity determine the behavior of molecules in electric fields?
How is polarity used in electrochemistry and batteries to drive chemical reactions?
Why don’t nonpolar substances mix with water, and how is this principle used in everyday life (e.g., oil spills)?
How does molecular symmetry contribute to nonpolarity?
What are examples of nonpolar molecules, and how are they important in biological systems?
