Question

Structure formula of \[{H_2}{O_2}\] is
(a)

(b) \[H - O - O - H\](Straight line).
(c) Where, \[\angle H - O - O = \angle O - O - H' = {101.5^o}\]and all the four atoms are in the same plane.
(d) Where, \[\angle H - O - O = \angle O - O - H' = {97^o}\]and the angle between \[H - O - O\]plane and \[O - O - H'\]plane is \[{101^o}\]

Answer 1

Hint: Hydrogen peroxide (\[{H_2}{O_2}\]) is the type of simplest known peroxide with oxygen-oxygen single bond. It has a non-planar and open book-type structure. Depending upon the reaction medium, it can behave like an oxidizing and reducing agent.

Complete step by step solution:Hydrogen peroxide is like water with an extra oxygen atom. Due to the presence of \[ - OH\] groups, it has an acidic nature( \[pH = 4.5\]).
Hydrogen peroxide is \[100\% \]degradable compound.
Hydrogen peroxide is considered as non-planar in nature with an open book-like structure.
The structure of hydrogen peroxide indicates the presence of an oxygen-oxygen single bond( \[O - O\]) with bond length \[145.5pm\]. Whereas the \[O - H\]bond length is around \[98.8pm\].
The non-planar open-book structure of hydrogen peroxide has two planes and both the planes contain \[OH\]group. The bond angle between both the planes is \[{90.2^o}\].
The bond angle between the \[H - O - O\]is \[101.{9^o}\].
The open-book structure of hydrogen peroxide can be represented as below.

Therefore from the above explanation we can say option (d) will be the correct option:

Note: The purest form of hydrogen peroxide is colorless in nature.
                          Hydrogen peroxide melts at \[272.4K\]and boils at \[423K\].
                          Hydrogen peroxide is miscible in water in all ratios.
                      The oxygen atom has -1 oxidation state in hydrogen peroxide.
                       Hydrogen peroxide is also used as a bleaching agent.
