Covalent Bonding and Carbon Compounds

The video tutorial explores how carbon forms covalent bonds by sharing electrons with other atoms. It begins by explaining the concept of valence electrons and how carbon, with its four valence electrons, forms stable molecules like methane (CH4) by bonding with hydrogen atoms. The tutorial then discusses carbon's ability to form double and triple bonds, using examples like carbon dioxide and acetylene. Finally, it examines more complex molecules, such as aspirin, to illustrate that carbon consistently forms four covalent bonds, ensuring stability in various chemical structures.
