{"knowledge_schema": {"broad_category": "Chemistry \u2192 Organic Chemistry \u2192 Stereochemistry", "refinement": "This problem involves the synthesis of a compound through a series of reactions that affect the stereochemistry of the product.", "specific_scope": "The focus is on the stereochemical outcomes of an SN2 reaction followed by an oxidation reaction, specifically how these reactions influence the number of possible stereoisomers of the final product.", "goal": "Determine the number of stereoisomers that can be formed from the final product after the specified reactions."}, "summary": "This problem is rooted in organic chemistry and specifically deals with stereochemistry. It involves two reactions: an SN2 reaction followed by oxidation with PCC. The first reaction leads to the formation of a chiral center, and the second reaction does not create any new stereocenters but can affect the configuration. The final product can exist in two stereoisomeric forms due to the presence of one chiral center, leading to the conclusion that there are 2 possible stereoisomers for the final product."}
