Sp² Hybridization in Ethene: The Secret of Double Bonds

The video tutorial explains the structure and bonding of ethane, focusing on its carbon-carbon double bond, which consists of a sigma and a pi bond. Ethane's SP2 hybridization results in a trigonal planar structure with a bond angle close to 120°. The double bond is strong, with a bond energy of 146 kcal/mol, and the pi bond has a shorter bond length of 1.34 angstroms. The tutorial visualizes the orbital structure, showing how SP2 hybrid orbitals form sigma bonds and how unhybridized p orbitals form pi bonds through lateral overlap, resulting in a delocalized orbital. The structure of ethane is also represented in different ways.
