SOLVED: Compare and contrast the IR spectrum of your benzil product to that of pure benzoin in the lab manual. You want to comment on ALL the peaks (or "stretches") that indicate a functional group that is unique to that substance. You should indicate location(s) (wavelength) and the type/identity of the functional group(s).IR Spectrum400035003000250020001500 Wavenumbers1000Infrared spectrum of benzoin, KBr:

SOLVED: The proton NMR spectrum of a compound of formula C10 H12 O follows. This compound reacts with an acidic solution of 2,4 -dinitrophenylhydrazine to give a crystalline derivative, but it gives a negative Tollens test. Propose a structure for this compound and give peak assignments to account for the absorptions in the spectrum. | Numerade
