WebApr 2, 2024 · Hint:Ozonolysis means the given organic compound will be treated with ${{O}_{3}}$ molecules.When an alkene is treated with ozone, then the double bond will break and all the three oxygen atoms will form a ring structure around the double bond and further on treatment with ZnO carbonyl compounds will form. The method was used to confirm the structural repeat unit in natural rubber as isoprene. It is also a serious problem, known as ozone cracking where traces of the gas in an atmosphere cause degradation in elastomers, such as natural rubber, polybutadiene, styrene-butadiene and nitrile rubber. Ozonolysis creates surface ketone groups which can cause further gradual degradation via Norris…
