An aldol condensation reaction was performed where benzaldehyde
and cyclopentanone were used. The product is 2,5
dibenzylidenecyclopentanone or just 2-benzylidenecyclopentanone.
The spectra correspond with the aldehyde being benzaldehyde but the
ketone used could either be acetone, cyclopentanone or cyclohexane.
I need to find the NMR spectra that correspond to cyclopentanone
being the ketone in the aldol condensation. Which NMR spectra
correspond to the correct product?
I think the second set is with cyclohexanone and not cyclopentanone but I could be wrong.
