Drawing Lewis Structure

Lewis Structure is the representation of electrons in the final orbitals of atoms by scattering them around the atomic symbol as dots. From the Lewis Dot Structure, it can be understood how many valence electrons an atom has and how many electrons this atom must acquire to achieve the noble gas arrangement.

If the two atoms that form a compound have exchanged electrons, the electrons given and received can also be represented by the Lewis dot structure.

Since covalently bonded compounds share electrons, these atoms can be brought together and the electrons they share can be shown with the lewis structure.

How to make lewis structures in ionic and covalent compounds is explained on this page.

In this section, the Lewis Dot Structure of organic compounds, which are covalently bonded compounds, by lewis structure will be explained.

Simple Formula

It is the smallest integers of the atoms in a compound. In this notation, the compound C2H4 can be represented as CH2 Lewis Structure. Only the types of atoms in the molecule and the ratios of atoms to each other can be understood from the simple Lewis Dot Structure.

Molecule Formula

The total number of atoms in a single molecule can be understood from the molecular formula. There are 3 C and 6 H atoms in 1 molecule of the C3H6 compound. This can be understood from the molecular formula. However, it cannot be understood from the simple formula how many atoms actually exist in 1 molecule of the compound. The simple formula of the compound C3H6 is CH2 Lewis Structure.

Lewis Structure

Lewis Structure is the representation of shared electrons with lines between atoms. A schematic representation of the molecule is made. In the Lewis Dot Structure, if one electron is shared between two atoms, a single line is drawn, if two electrons are used together, a double line, and if three electrons are used together, three lines are drawn. Each line drawn represents a total of two electrons, one from each atom in Lewis Structures.

A single line between atoms indicates a single bond, a double line indicates a double bond, and three lines indicate a triple bond. One electron each in a single bond, two electrons in a double bond, and three electron pairs in a triple bond are shared between atoms. Lewis Dot Structure can be drawn in that way.

Bond Degree

It is the number of bonds that join certain atoms in a molecule. If there is only one bond between two atoms, the degree of bond is 1, if there are 2 bonds, the degree of bond is 2, if there are 3 bonds, the degree of bond is 3.

Sample:

Let us show the Lewis dot structure of the C3H8 molecule.

The number of valence electrons of the C atom is 4, and the number of electrons of the H atom is 1. The C atom can form 4 bonds, and the H atom can form a single bond. The atom with the most bonds is placed in the centre of Lewis Structure.

Let’s place the valence electrons of the C atoms around and bring these atoms side by side.
2- Hydrogen atoms contain 1 valence electron. Let’s place the H atoms with the valence electron facing the C atom.

You might be interested in: What is Lewis Dot Structure?

3 C atoms and 8 H atoms arranged around it. Both C atoms and H atoms have completed their valence electrons to 8. Here, the 3 C atoms have shared their electrons both with the H atom and with each other. Namely,

3 C atoms have a total of 3.4 = 12 valence electrons.

8 H atoms have a total of 8 valence electrons.

C atoms share 8 of their valence electrons with H atoms. There are 4 valence electrons left.

The remaining 4 valence electrons are shared by the C atoms.

Another point to be noted here is that the electron pair used jointly between C – C and C – H atoms is 1. This indicates that the bond between all atoms is a single bond.
