* Electronegativity: Electronegativity is the ability of an atom to attract electrons towards itself in a chemical bond. Oxygen is highly electronegative, meaning it has a strong pull on electrons.
* Polar Covalent Bond: When oxygen bonds with carbon, they form a polar covalent bond. This means that the electrons in the bond are not shared equally. The more electronegative oxygen atom pulls the electrons closer to itself, creating a partial negative charge (δ-) on the oxygen and a partial positive charge (δ+) on the carbon.
* Effect on Carbon: This partial positive charge on the carbon makes it more susceptible to attack by nucleophiles (electron-rich species) in chemical reactions.
In summary: The presence of an oxygen atom attached to a carbon makes the carbon more electronegative due to the polar nature of the bond. This has implications for the reactivity and properties of the molecule.
