Question

In case of $H_2{O}_2$ in solid state, the angle between the planes containing $H-$atoms is:

• A. ${100}^o$
• B. ${90}^o$
• C. ${109}^o{28}^{{}^{\prime }}$
• D. ${180}^o$

Answer 1

Answer: (B)

${90}^o$

There are two planes in this structure and each plane has one O-H pair, the angle between both the planes is 90.2°, The O-O bond length is 145.8 pm and the O-H bond length is 98.8 pm.

Hence option B is correct.
