Oxygen Containing Compounds - Keto Acids and Esters
WebWhen beta keto acid is heated, it releases carbon dioxide gas, thereby forming acetone. Acetone is a type of ketone. This is an intramolecular H-bonding between 'O' and 'H' of beta-keto acid, thereby breaking its pie bond. Electron moves to the direction where there is a deficiency in releasing carbon dioxide. Web5 de mar. de 2024 · The simple aliphatic carboxylic acids do not lose carbon dioxide on heating, but when there are strongly electron-attracting groups attached to the α carbon, … skyray aircraft
