  Identify the reducing agent in the following reactions. (a) (b) (c) (d)

Answer:

    (a)is the reducing agent because it gives hydrogen and itself gets oxidized to NO(Removal of H and addition of O). O2 has been reduced to H2O (Addition of hydrogen). (b) H2O is the reducing agent because of the addition of electronegative F to get oxidized to HOF. It reduces F2to HF (by addition of hydrogen). (c) has been reduced to Fe (Removal of oxygen). Also, CO has been oxidized to CO2(Addition of oxygen) and hence, CO is a reducing agent, (d) H2 is the reducing agent which itself gets oxidized to H2O (Addition of oxygen). O2 has been reduced to H2O (Addition of hydrogen).
