This is my first time taking organic chemistry, but you have been my tutor for calculus, gen chem, and basic math. I am so happy to finally use your videos for organic chemistry because thats the name of your channel haha

I wish all professors taught like him, my professor just put a question on the board and leaves class and hopefully we’ll figure it out. He even told us that we don’t have to read the book, which i think is a joke bc I’ve learned so much from reading the book than in his class, its like my edu is a joke to him, bless the organic chem tutor I wouldn’t have made i through with out your wonderful videos

Of course it's always necessary to have a basic introduction to IR spectroscopy, and this video does so at a quick rate and so well. And of course again, I love this channel on youtube because not only do you explain a concept but provide practice problems in order to better understand IR spectroscopy.

Thank you very much sir...and I have one confusion...in this video while explaining about conjugation , u said conjugated alkene absord higher energy at lower wavenumber ....but energy and wavenumber are directly related...pls explain this.

@tasukedate8180 Жыл бұрын

When he said wave umber, he was referring to the x axis on an IR spec graph. For example, a ketone is found at 1720 cm-1. But if the ketone is conjugated, the number changes to 1680 cm-1. Generally, conjugation lowers the wave number by. 40.

Can someone please explain to me why the non-conjugated ketone (around 14:50) can't do resonance yet the conjugated ketone can? Thank you.

@bacchus9389 2 жыл бұрын

If you try to move the double bond that isn’t the ketone on the left molecule, you’ll give some carbons more than four bonds, so you don’t get an additional resonance form (so you’ll get the double bond from the ketone moving but not any additional ones). The right one participates in resonance because the double bond is right next to the ketone, so it can “fill in” the positive charge left by the ketone, so you get an additional resonance form with that double bond being able to be moved over.

A wave number is the reciprocal of the wavelength its 1/wavelength hence its in cm-1

@@karaborose1940 I still don't understand. So, why don't just call wave length, as physic only knows wavelength or frequency?

@HughCStevenson1 2 жыл бұрын

@@StrsAmbrg Wavenumber is proportional to frequency and energy of the photon. The only reason that the weird cm-1 unit is used is because spectroscopist chemists haven't caught up with the SI unit system! :) No, seriously, it is just a convention. Annoying to me. Using an energy based unit (as contrasted to wavelength) is that energies can be added and subtracted and the maths works out. Because wavelengths are inverse it doesn't.
