The `O-O-H` bond angle in `H_2O_2` in the gas phase is

A

`106^(@)`

B

`109^(@)28`

C

`120^(@)`

D

`94.8^(@)`

Text Solution

Verified by Experts

The correct Answer is:
D
The structure of `H_(2),O_(2)` in the gaseous phase is

Hydrogen peroxide is a dihydroxy compound (H-0-0-H) and the O-O linkage is known as a peroxide linkage. It is a non-linear molecule as the two O-H bonds are in different planes. The interplanar (dihedral) angle is `111.5^(@)` in the gaseous phase, but it is reduced to `90.2^(@)` in the crystalline state because of hydrogen bonding.
