Concept introduction:
Formation of
The
(b)
Interpretation:
The optically active Oxirane formed by the given reaction has to be explained.
Concept introduction:
Formation of epoxide:
The alkene can be converted into epoxide, when it is treated with MCPBA (m-chloro per benzoic acid).
Chirality: The presence of four different atoms (or groups) at carbon is known as asymmetric carbon and is known as chiral center of the compound. Chiral compounds are optically active.

In the first step, G undergoes a Wittig reaction, leading to the formation of an alkene, H. Subsequently, H is treated with an ozone (O3) reagent followed by a reducing agent in an ozonolysis reaction, resulting in the formation of two different products, I and J. Considering the functional groups present in G and the nature of the reactions involved, what are the most probable structures or functional groups present in products I and J? A. I contains a carboxylic acid group, and J contains an aldehyde group. B. I contains a ketone group, and J contains an alcohol group. C. I and J both contain aldehyde groups. D. I contains an ester group, and J contains a ketone group. Don't use chat gpt.arrow_forward
