Chapter 18.10, Problem 18.13P

Interpretation Introduction

Interpretation:

Electron dot structure for $H_2{O}_2$ has to be drawn. Check whether the structure is consistent with its $\text{O-O}$ bond length of $148pm$ or not.

Concept introduction:

Electron dot structure is a representation of covalent bonding that indicates where the valence shell electrons are in the molecule. Shared electron pairs are shown as lines and lone pairs are shown as dots.

Example:

Bond order describes, if a bond is single bond order is one, if it is double bond order is 2.

Bond length is the distance between the centers of two atoms joined by a covalent bond.

Higher bond order corresponds to shorter bond length.

The bond length and bond order of some molecules are listed below,

$\begin{array}{ccc}Bondtype& Bondorder& \begin{array}{l}Bondlength\\ \left(pm\right)\end{array}\\ C-C& 1& 154\\ C=C& 2& 134\\ C\equiv C& 3& 120\\ O=O& 2& 121\\ O-O& 1& 148\end{array}$
