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...
The table below provides shipping rates for packages using UPS next day air or ground service options. The rates vary according to both the weight of the package and the distance of the shipment (larger numbered zones are farther away). Note that the zone number also indicates the number of days required to deliver a package using ground service. For example, it would take three days and cost $7.40 to send a 10-pound package to zone 3 using ground service....
