Question. The UV spectrum of an unknown compound shows values ofat 225 nm(E = 10,000) and at 318 nm(E = 40). The mass spectrum shows a molecular ion at m/z 96 and a prominent base peak at m/z68. The IR and NMR spectra follow. Propose a structure, and show how your structure corresponds to the observed absorptions. Propose a favorable fragmentation to account for the MS base peak at m/z 68 (loss of C2H4 ).
Rank the following compounds in order of increasing amount of hydrate present at equilibrium.
Sketch the expected proton NMR spectra of 3,3- dimethylbutanal.
Propose a mechanism for both parts of the Wolff-Kishner reduction of cyclohexanone: the formation of the hydrazone, and then the base catalyzed reduction with evolution of nitrogen gas.
