      Match the items of Column I and Column II on the basis of data given below

Answer:

                  A. ® (3)   B. ® (1)   C. ® (7)   D. ® (5)   E. ® (4)   F. ® (2)   G. ® (6) A. F2 is a non-metal and best oxidising agent because SRP of F2 is + 2.87 V. B. Li is a metal and strongest reducing agent because SRP of Li is - 3.05V.     C. Au3+ is a metal ion which is an oxidising agent as SRP of Au3+ is +1.40 V. D. Br- is an anion that can be oxidised by Au3+ as Au3+ (E° = 1.40) is greater than                       Br-(E°= 1.09V). E. Au is an unreactive metal. F. Li+ is a metal ion having least value of SRP (- 3.05 V), hence it is the weakest oxidising agent. G. F- is an anion which is the weakest reducing agent as F- /F2 has low oxidation potential (-2.87V).
