Dichlorine monoxide is an one oxide of chlorine. It contains two chlorine atoms and one oxygen atom and we will learn how to draw the lewis structure of Cl2O step by step in this tutorial.
Lewis structure of Dichlorine monoxide (Cl2O) contains two Cl-O bonds. Oxygen atom is the center atom and both chlorine atoms are located around that center oxygen atom. There are no charges on chlorine and oxygen atoms in Cl2O and we will learn how to draw the lewis structure of Cl2O in this tutorial.
According to the lewis structure of Cl2O, there are two lone pairs on oxygen atom and each chlorine atom has three lone pairs.
When we draw a lewis structure, there are several guidelines to follow. Number of steps can be changed according the complexity of the molecule or ion. Because Cl2O molecule is a simple molecule and there is no overall charge, some of these steps are not required to use. However those all steps are mentioned and explained in detail in this tutorial.
There are two kind of elements in hydrogen peroxide; chlorine and oxygen. Chlorine is a group VIIA element in the periodic table and only has 7 electrons in its last shell (valence shell). Oxygen belongs to the group VIA and contains 6 electrons in its valence shell shell. Now, we know how many electrons are there in valence shells of chlorine and oxygen atoms.
Total valance electrons pairs = σ bonds + π bonds + lone pairs at valence shells
Total electron pairs are determined by dividing the number total valence electrons by two. For, Cl2O, Total pairs of electrons are 10 in their valence shells.
To be the center atom, ability of having greater valance and being most electropositive element in the molecule are leading facts.
After determining the center atom and skeletal of Cl2O molecule, we can start to mark lone pairs on atoms. Remember that, there are total of 10 electron pairs.
There are no charges on oxygen atom and chlorine atoms. Remember that Cl2O is a molecule which does not have an overall charge. Therefore, we don't need to do the final step of reducing charges of atoms to obtain most stable lewis structure.
