(b)
Interpretation:
The given conversion is to be accomplished with the help of enamine synthesis using pyrrolidine as the secondary amine.
Concept introduction:
When aldehydes or ketones react with a secondary amine, formation of enamine takes place. The nitrogen analog of an enol is known as enamine. From the resonating structures of enamine, it is clear that it nucleophilic in nature. Reactivity of enamines is higher than an enol but less than an enolate ion. Milder conditions are favourable for enamine reactions.

- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
