Consider the following reaction : 2 HSO 4 - aq 1   Electrolysis 2   Hydrolysis 2 HSO 4 - + 2 H + + A The dihedral angle in product A in its solid phase at 110   K is

Options

  1. A104 °
  2. B111 . 5 °
  3. C90 . 2 °
  4. D111 . 0 °

Correct answer

C. 90 . 2 °

Step-by-step solution

Peroxodisulphate, obtained by electrolytic oxidation of acidified sulphate solutions at high current density, on hydrolysis yields hydrogen peroxide. 2 HSO 4 - ( aq ) ⟶   Electrolysis HO 3 SOOSO 3 H ( aq ) → Hydrolysis 2 HSO 4 - ( aq ) + 2 H + ( aq ) + H 2 O 2 ( aq ) Hydrogen peroxide has a non-planar structure. The molecular dimensions in the gas phase and solid phase are shown H 2 O 2 structure in gas phase, dihedral angle is 111 . 5 ° . H 2 O 2 structure in solid phase at 110   K , di
