Phosgene Structure and Properties

The video tutorial explains the molecular and structural formulas of phosgene, also known as carbonyl dichloride. It begins with an introduction to the molecular formula COC12, emphasizing the importance of not confusing it with cobalt. The tutorial then discusses the IUPAC name, carbonyl dichloride, and its significance in understanding the compound's structure. The structural formula is detailed, highlighting the arrangement of carbon, oxygen, and chlorine atoms. Finally, the video overlays a Lewis structure to illustrate the lone pairs on oxygen and chlorine, providing a comprehensive understanding of phosgene's chemical structure.
