The kinetics of the isotope exchange reactions of RCH(COOH) 2 (R"H, D, Me, Et, Bu, and Ph) in D 2 O solution were studied by using 1 H NMR spectroscopy. It was observed that the rate of isotope exchange reaction was inhibited by the presence of 1 M of DNO 3 , DCl, DBr or D 2 SO 4 and catalyzed by th
