When we look at the Lewis structure of H2CO3, we can see that H has one, C has four, and O has six electrons in the outer shell. The hybridization of the central atom ( Carbon ) in CH3OH is sp3, which means that it should form a tetrahedral shape, but it doesn’t form this shape exactly. Finally, this is our NH2- Lewis structure diagram. A. The molecule’s structure is easy to understand, and one can also use this example to study more complex structures in organic chemistry. Carbon has a steric number of 4 as it has four valence electrons in its outer shell.

And if not writing you will find me reading a book in some cozy cafe ! Molecular geometry doesn't consider the lone pairs as bonds like in electron domain geometry (really bad wording, but that's the gist of it). To know the total number of valence electrons, we have to know the valence electrons of all the atoms individually: Carbon has four valence electrons in its outer shell, hence the valence electrons in Carbon= 4. Now that we know the Lewis structure of CH3OH, it is easy to depict the compound’s molecular geometry. This compound has a hydroxyl group ( OH) attached to the methyl group, and that is where it gets its name of “methyl alcohol.” To make it easier for you to understand, assume that one hydrogen atom of methane or CH4 is substituted by a hydroxyl group, resulting in Methanol having the chemical formula of CH3OH.Â. Yet More Lewis Structures. Still, there are four valence electrons on the Oxygen atom that forms two lone pairs of electrons around it.  Thus all the valence electrons of the Carbon atoms have now formed bonds, and there are no lone pairs or non-bonded electrons on the central Carbon atom but Oxygen has two lone pairs of electrons. 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.Â. 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.
