Reduction potentials of four elements P, Q, R, S is − 2 .90 V , 0.34 V , 1 .2 V and − 0 .76 V . The decreasing order of reducing power is

Options

  1. AP > Q > R > S
  2. BS > R > Q > P
  3. CP > S > Q > R
  4. DQ > S > R > P

Correct answer

C. P > S > Q > R

Step-by-step solution

Reducing power, i.e. the tendency to lose electrons increases as the reduction potential decreases
