Why gama lactone is formed not other?
Gamma-lactone is primarily formed due to the intramolecular esterification of hydroxy acids, where the hydroxyl group reacts with the carboxylic acid group within the same molecule. This specific structure allows for the formation of a five-membered ring, which is energetically favorable compared to the formation of larger or smaller lactones. The stability and strain-free nature of the five-membered ring make gamma-lactones particularly favorable in various chemical contexts, leading to their predominance over other lactone types.
