ковалентная полярная

Answer 2

H2C2O4, also known as oxalic acid, is a compound rather than a simple substance. It is a dicarboxylic acid with the chemical formula C2H2O4. Oxalic acid is a colorless, crystalline solid that is highly soluble in water. It is commonly found in plants and can also be produced synthetically.

Regarding its polarity, oxalic acid is a polar molecule. The presence of two carboxyl groups (-COOH) in its structure gives it a polar nature. The oxygen atoms in the carboxyl groups have a higher electronegativity than the carbon and hydrogen atoms, creating a partial negative charge on the oxygen atoms and a partial positive charge on the carbon atoms. This polarity allows oxalic acid to form hydrogen bonds with water molecules.

In summary: - H2C2O4 is a compound, specifically a dicarboxylic acid. - It is commonly known as oxalic acid. - Oxalic acid is a polar molecule due to the presence of carboxyl groups in its structure.
