  • Resonance is a way of describing delocalized electrons within certain molecules where a single Lewis formula cannot express the bonding. To understand resonance in chemistry, you need to first understand covalent bonds, sigma and pi bonding and Lewis structures.
    There are three main types of bonds, dependent on the number of electrons shared between atoms. If two atoms within a molecule share a single pair of electrons, a single bond is formed between the atoms. Similarly, double and triple bonds are formed when two atoms share two and three pairs of electrons, respectively.
    Covalent bonds also come in two types: sigma bonds and pi bonds. A Lewis Structure is a tool to represent valence shell electrons in a molecule. A Lewis structure shows the arrangement of electrons around individual atoms in the molecule. Electrons are shown as dots, while bonding electrons are denoted as a line between the two atoms. electrons in sigma bonds tend to be in specific locations, which is why those electrons are said to be localized, whereas pi bonds have delocalized electrons; these are found above and below the atoms and are spread across several atoms. The idea of resonance helps us understand and describe molecules that a single Lewis structure cannot represent. The various resonance structures show different possibilities of the electrons’ positions in the molecule.

    Resonance brings stability to molecules. That’s the most important point I think.

    I struggled with this soo much and it was explaained soo well thank you soo much.. Lol. :D Format of videos is fantastic.

    Ah, I think you should probably have made clear you were talking about "electron resonance" in this vid's title, rather than "general resonance", to avoid people watching when it's not actually what they were looking for.
    Great vid, though. Just a misleading title :)

      Thanks for the feedback! We have changed the title.

    Time 4:13 😅 why the benzene kill the Lewis structure like that 😅😂

      You clearly have no idea how hard they work just to make these animations each and every single video.
      It’s a shame that it only got 1.4K views so far, and a shame you were one of them rather than someone more appreciative of these very good, very down to earth and excellently explained science videos.

      you clearly have no idea how easy it is to make these@@maksimatic
