Problem #23: When compound X (C,H,Br) is reacted with sodium cyanide (NaCN) forms compound Y (C,H,N). Compound Y, upon reduction with H over a Ni catalyst, yields compound Z (C,HIN. The 'H NMR spectrum of X gives two signals, a multiplet at δ = 7.3 ppm (5H) and a singlet at δ 4.25 ppm (2H). The 'H NMR spectrum of Y is similar to that of X in that it shows a multiplet at ö-7.3 ppm (5H) and a singlet...

Compound A (C11H16O) has a band in the IR spectrum at 3450 cm-1 (strong, broad) and does not react with pyridinium chlorochromate (PCC) in CH2CI2. Compound A does react with HBr to give compound B (11H15Br). Compound B reacts with potassium f-butoxide to give compound C (C11H14). Ozonolysis of C followed by treatment with Zn and water gives CH3CHO and compound D (C9H10O). The proton NMR spectrum of compound D is given below. Treatment of compound D with ethyl magnesium...
