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_2O_2` in the gaseous phase is
Hydrogen peroxide is a dihydroxy compound (H-O-O-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 ofhydrogen bonding.
