Options
- A104 °
- B111 . 5 °
- C90 . 2 °
- 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
