Question
Which of the following is weakest oxidising agent ?
Options
A.F2
B.Cl2
C.Br2
D.I2
Solution
F2 + 2e- → 2F- εo = + 2.87 V ; Cl2 + 2e- 2Cl- εo = + 1.36 V
Br2 + 2e- → 2Br- εo = + 1.09 V ; I2 + 2e- → 2I- εo = + 0.54 V
More the value of the SRP, more powerful is the oxidising agent. Hence the order of oxidising power is
F2 > Cl2 > Br2 > I2.
Br2 + 2e- → 2Br- εo = + 1.09 V ; I2 + 2e- → 2I- εo = + 0.54 V
More the value of the SRP, more powerful is the oxidising agent. Hence the order of oxidising power is
