Question

Match the items of Column I and Column II on the basis of data given below:
(One to one match only)
`E_(F_(2)|F^(-))^(@)` = 2.87 V, `E_(Li^(+)|(Li)` = -3.5 V,
`E_(Au^(3+)|Au)^(@)` = 1.4 V, `E_(Br_(2)|Br^(-))^(@)` = 1.09V

Answer 1

A. `F_(2)` is a non-metal and best oxidising agent because SRP of `F_(2)` is +2.87V
B. Li is a metal and strongest reducing agen t because SRP of `Li` is -3.05V
`Au^(3+)` is a metal in which is an oxidisng agent as SRP of `Au^(3+)` is +1.40V
D. `Br^(-)` is an anion that can be oxidised by
`Au^(3+)` and `Au^(3+)(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(-3.05V), hence it is the weakest oxidising agent.
G. `F^(-)` is an anion which is the weakest reducing agent as `F^(-)//F_(2)` has low oxidation potential `(-2.87V)`.
