Amazing video man, I'm a studying chemistry at UC Berkeley and you explain way better than any professor! Don't know why you don't have more subscribers!
When I followed your calculations I got 219 nm in comparison to 614 nm (experimental value). I think I did something wrong in the calculations but at the same time my teacher said that there should be a significant difference. I'm not sure of the reason for this though. Any suggestions please.
That is true given the resonance structures, you could use a 1.5 bond for all of them. But its equally good to use the double bond length for half the bonds and the single bond length for have the bonds. This will give the same length.
Hi Adiraju, You fill electrons in from the lowest energy up, first singly, then paired, until you run out of electrons. This is similar to orbital diagrams from general chemistry. You might check out a video on this process to fill in the gaps. I hope that helps! Dr. Morris

Why can't my professor teach this simple. Thank you so much!
I dont understand why the box ends just before the rings. Are the rings not also conjugated bonds?
Because the potential energy outside the box is infinite. Thing about the sin curve

I think the calculation of length is wrong. He used lengths of double bond and single bond whereas the actual length is between them((133+154)÷2)

how does the benzene molecule model a wall? its conjugated with the chain.
Very helpful thank you!
Can you help me in predicting max wavelength for π-π* absorption band in UV spectrum for compound 3-methyl Pent-3ene-2one ...plzzzz
doesn't the electron have an effective mass?
This is great!
Thank you!
I didn't understand how you filled electrons just by using gen chem
