Hydrogen peroxide has a non-planar structure. In gas phase of H_(2)O_(2), dihedral angle is v^(@) and in solid phase at 110 K, its dihedral angle is y^(@). What are x and y ?

Answer»

`90^(@), 90^(@)`
`90.2^(@), 101.5^(@)`
`111.5^(@), 90.2^(@)`
`90.2^(@), 119.5^(@)`

SOLUTION :Structure of `H_(2)O_(2)` is slightly different is GAS phase and CRYSTALLINE phase.
