Chapter 7, Problem 7.11P

Interpretation Introduction

Interpretation:

The best electron-dot structure for the ClO₂ radical is to be selected.

Concept introduction:

Electron-dot structure represents valence electrons of an atom by dots and show how they are distributed in a molecule. Every atom tries to a complete valence shell or to achieve noble gas configuration by making bonds with other atoms.

Most of the compounds have even number of electrons hence, paired up. But there are several compounds which are called radicals have odd number of electrons. So, radicals have unpaired electron.
