Valence Electrons in Methanol

The video tutorial explains the Lewis structure for methanol. It begins by identifying the valence electrons for carbon, hydrogen, and oxygen, totaling 14. The structure is built by placing carbon at the center, surrounded by three hydrogens, and adding oxygen and another hydrogen. Chemical bonds are formed by placing two electrons between atoms, ensuring all hydrogens have two electrons and carbon and oxygen have eight. The tutorial concludes with a complete Lewis structure for methanol, with all octets satisfied.
