Understanding Ethene and Its Properties

The video tutorial explains the structural formula of ethene, also known as ethylene. It begins by introducing ethene and its molecular formula, C2H4, and explains the significance of the 'ene' suffix, indicating an alkene with a double bond. The tutorial then guides viewers through drawing the structural formula, highlighting the placement of the double bond between two carbon atoms and the attachment of hydrogen atoms. A visual model of ethene is presented, showing the carbon and hydrogen atoms. The video concludes by summarizing ethene as the simplest alkene with a double bond.
