WebMar 4, 2024 · Explain the ozonolysis of (a) Acetylene (b) Propyne Answer: Ozone adds to carbon-carbon triple bond of alkynes to form ozonides. The ozonides are hydrolysed by water to form carbonyl compounds. The hydrogen peroxide formed in the reaction may oxidise the carbonyl compound to carboxylic acid. WebMechanism: Three steps are involved in the ozonolysis reaction mechanism. Step 1: Attack of ozone molecule. The ozone molecule has one positively and one negatively charged oxygen atom. The exchange of electrons between alkene having bond and ozone molecules result in a cyclic structure known as molozonide.

WebAny arrangement with three O atoms in a row is unstable. That is why ozone, :O-O=O:, is so reactive in the first place. The five-membered ring formed by the reaction of ozone with the ring, called a molozonide, is still highly unstable, because it still has 3 O atoms in a row.It could decompose back into ozone and the original alkene, but if it decomposes as in the …
