    it might be the best channel ever you can find in RUclips explaining organic chemistry in a beautiful delicate way

    i must say @knowbee this is wonderful thing that you people are doing to teach all basic things despite being busy in your lives , I appreciate your start up and will continue to learn :)

    Sir plz keep doing the great job u do.. I don't know what are the last three vdos u posted... But ur chemistry is best the way u teach is remakable... Truly a gem..

    Thank you! This was incredibly informative. I have to present a paper written by my professor and this made interpreting the UV-VIS data more understandable.

    6:34 all four orbitals are pi orbitals. Sigma and sigma antibonding orbitals chacterize another bond between carbons and they both have axis of symmetry that is why the are called "sigma".
    It is interesting (but rarely done) to regard the symmetry according inversion center if this is S-trans 1,3-butadiene. Then you can illustrate the allowed (between g and u and vise versa) and forbidden (g -> g and u -> u transitions. u = ungerade, g = gerade). I do it for my students.

    One correction: It's all pi-bonding. The pi-system (the double bond(s)) is made up of unhybridized p-orbitals. The unhybridized p-orbitals aren't sigma-bonding. Even your figures show pi-bonds - the vertical arrangement of orbitals side-by-side.

    If atomic orbitals are overlapping laterally then how can you say it as a sigma bonding MO. It should be pi Mo.

    If you are showing molecular orbitals made from side by side overlap of p atomic orbitals, then all the resulted molecular orbitals should be called pi. There shouldn't be any sigma and sigma star in the diagram. This video is graeat, the only mistake is the one that I and others have mentioned in the comments, so please reupload the video.
