How to do a lewis structure for ch4 on chemdoodle

There are a total of 14 valence electrons in the compound. Valence electrons help in drawing this Lewis structure, as all the electrons are shown by using dots, and the straight lines represent the bonds formed between the molecules. It helps in knowing the number of bonded electrons, lone pairs, and the compoundвЂ™s molecular shape. Lewis dot structure is a pictorial representation of the molecule, itвЂ™s bonding with other atoms and the arrangement of atoms in the compound. This rule has some exceptions in chemistry, but majorly, all elements follow this octet rule. Hence all the atoms tend to form bonds in achieving this configuration and become stable. In chemistry, all the atoms tend to become inert by attaining the electronic configuration of the noble gas that has eight electrons in its outer shell. Thus the total number of valence electrons in CH3OH ( Methanol) is 14. Total number of valence electrons in CH3OH = 4 + 3+6+1 Hydrogen attached to the Oxygen in the hydroxyl group has one valence electron hence its valency is 1. Oxygen has six valence electrons in its outer shell and needs two electrons to follow the octet rule hence its valency is 6. Hydrogen has only one valence electron, but as there are three Hydrogen atoms in this compound, the total number of valence electrons for Hydrogen = 3*1= 3.

To know the total number of valence electrons, we have to know the valence electrons of all the atoms individually:Д¬arbon has four valence electrons in its outer shell, hence the valence electrons in Carbon= 4. Methanol consists of one carbon atom, three Hydrogen atoms, and one hydroxyl group.
