Identify the compounds produced in these reactions. Warning! Do not attempt to deduce the structures from the starting materials but use the data! These molecules are so small that you can identify them from 'H-NMR alone. RCO3H LII NANH2 > A B - t-BUOH Compound A: SH(C4H6) 5.35 p.p.m. (2H, s) and 1.00 p.p.m.(4H, s). Compound B: 8H(C4H6O) 3.00 ppm (2H, s), 0.90 ppm (2H,d, J 3 Hz), and 0.80 ppm (2H, d, J 3Hz). Compound C: SH(C4H6O) 3.02 ppm (4H, d, J 5 Hz) and 1.00 ppm (2H, quintet, J 5 Hz).
