Definition: In chemistry, a "aryballoid" is a type of organic compound that forms a stable chemical bond between two or more atoms. These compounds are often used as catalysts in chemical reactions because they can increase the rate of certain chemical reactions by providing a high-energy electron transfer pathway. Examples of aryballoids include ethylene (C2H4), propene (C5H10), and naphthalenes, which have both a carboxylic acid group and a
