NEET 2020 Chemistry Ozonolysis of Alkenes MCQ Question

The structure in option A is a 1-alkene that, upon ozonolysis, undergoes cleavage of the carbon-carbon double bond. This reaction results in the formation of methanal (formaldehyde) as one of the products, specifically when the double bond is located adjacent to a terminal carbon. The ozonolysis reaction effectively breaks the double bond and adds oxygen, leading to the production of aldehydes or ketones, confirming that option A is the correct structure.
