WebFormation in soft drinks. The major cause of benzene in soft drinks is the decarboxylation of benzoic acid in the presence of ascorbic acid (vitamin C, E300) or erythorbic acid (a diastereomer of ascorbic acid, E315). Benzoic acid is often added to drinks as a preservative in the form of its salts sodium benzoate (E211), potassium benzoate (E … WebBenzene is a closed ring of six carbon atoms linked by bonds that alternate between single and double bonds. Each carbon atom is bound by a single hydrogen atom. Benzene melts at a temperature of 5.5 ° C, boils at 80.1°C. Benzene and its derivatives are part of an essential chemical community known as aromatic compounds.
Web18 sep. 2024 · Benzene is built from hydrogen atoms (1s 1) and carbon atoms (1s 2 2s 2 2p x1 2p y1 ). Each carbon atom has to join to three other atoms (one hydrogen and two carbons) and doesn't have enough unpaired electrons to form the required number of bonds, so it needs to promote one of the 2s 2 pair into the empty 2p z orbital.
