Still, there are four valence electrons on the Oxygen atom that forms two lone pairs of electrons around it. There are four valence electrons left in the outer shell of the oxygen atom as it shares one of its six valence electrons with Hydrogen and another one with the Carbon atom. Hydroxyl group ( OH) shares one valence electron with Carbon, and thus this hydroxyl group forms one bond with the Carbon by sharing its valence electron. To represent these bonds, draw straight lines between three Hydrogen atoms and the central carbon atom. Now all the Hydrogen atoms have one valence electrons, and all these three atoms form a bond with Carbon by sharing one electron of the Carbon atom. In Methanol, Carbon is the central atom, and all the other atoms are placed around it.įor drawing the structure, you can place four electrons ( as dots ) around the central carbon atom in all four directions. Carbon has a steric number of 4 as it has four valence electrons in its outer shell. 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 compound’s molecular shape. Lewis dot structure is a pictorial representation of the molecule, it’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. ![]()
