You are like one of the few channels to do such an elegant video on the topic. Simple , logical , straight forward, there aren't 4 arrows in one step. All the other channels show this mechanism with so many arrows cluttered together. I don't know why they show it like this , is it supposed to be simpler?

Mechanisms can never be proven, but I believe this is a reasonable way to understand it!

Thank you very much,Wentzel lab. Very helpful and love your explanation. Chemistry students from University of Papua New Guinea. Could you also make videos on ways or skills to answer combined spectrum exam questions quickly and steps to write solutions of each spectra easily y.

Sir, I created a Google account just so I can subscribe to you and like this video, I have been taking organic chemistry for 5 months and barely understood what was going on. I was stuck on this chapter after my first lecture this semester so I go on to youtube to search up HOMO and LUMO, and I just have to say I came across the best video on youtube. You deserve more than just 1.06k subscribers and I'm sorry I can only add one more to that. Thank you so much for your service sir it's highly appreciated.

If I have solid sample containing components, can I use any solvent to dissolve it? Or I have to use only the same mobile phase as solvent to dissolved sample? Another case, if must use same mobile phase, but my sample can not dissolve, here, please I need solution to this problem. can I use any solvent? thank you alot in advance

happy new year and Thank you so much for this video. Is there standard to use silica gel in column, I mean if my sample a little bit like (0.01 gram), how much of silica gel use here? in contrast, if I have a lot of samples such as (1 gram or more), here, how much of silica gel have to use? I mean is there ratio from silica gel to sample to use in column, please tell me

i'm a little confused. For the second problem, wouldn't the Nitro group add second since it's a meta director, so it can add the Br in the meta position last?

@wentzellab9707 2 жыл бұрын

Nitro group needs to go on last since it is a deactivator! Activating groups that donate electrons are more important for directing!

@kathryn1946 2 жыл бұрын

@@wentzellab9707 if you add the nitro group on last, wouldnt the bromine direct it o/p to bromine because it is a stronger director due to its lone pairs that it can donate?

@wentzellab9707 Жыл бұрын

@@kathryn1946 The alkyl group will be the one directing since it is an activating group. The Br can donate and direct o/p but it does not want to do that as a deactivator!
