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...
