Covalent Compounds and Molecular Models

The video tutorial discusses whether C3OH, known as methanol, is ionic or covalent. It explains that methanol is a covalent compound because it consists of nonmetals bonded together. The video uses the periodic table to identify carbon, hydrogen, and oxygen as nonmetals, leading to covalent bonding. Various representations of methanol's molecular structure are shown, highlighting the shared electron pairs that form covalent bonds. The tutorial concludes by reinforcing that methanol is a covalent compound due to its nonmetal composition and shared electron pairs.
