You make chemistry so easy. No sweat! I hope you were my professor so I would always understand CLEARLY each lesson. I love your tutorials! :)

one quick way to remember ( for 2 of them) the group attached if you hear the name: phenol ends in -ol just like alcohols, aniline has "an amine"

I could see comments 5 yrs ago and more from previous years.. but in recent times I can't find a lecture vid in less duration with good explanation. Until I found this, it's a saviour at last minute ❤ I can understand very clearly. And it also saves my time.

Thanks for taking time to do this. You really clarified my ideas A LOT. Looking forward to watching new videos.

One advice, Go to settings and increase the speed by 1.25 times. He's a good teacher though.

Yeah, speeding up these videos are useful when in a time crunch. If not, it's more relaxing to learn slowly, I guess...

My lecturer makes it seem so difficult to understand yet you explain it so well. I LOVE YOU SAL! No Bromo!

Thank you very much good sir, you've helped me with my studies!

Super awesome!! Love this channel!! You helped a lot, as usual :)

Your voice is always consistent :] Even from your older videos. Anyway, thanks for your help!

Amazing, thank you so much!! :)

8:35 shouldn't it be called benzenal? Because the suffix for aldehyde is al ?

What kind of program do you uses for this videos? I love this writing.

really interesting....thanks a lot.....

This is cool...thanx dude...

At 11:22 min, can vannillin be named as , meta methoxy- para hydroxy - benzaldehyde?

Thank you!

If we have both amine and methyl group on benzene then from where we should start numbering and why??

Thank you so much 🌷❤️

I can't believe that this video is 13 years ago's video.🎉❤

thanks a lot !!

How to naming a chemical the Benzene which 6 Hydrogen atoms are replaced by F, Cl, Br, NO2, OCH3 and CH=CH2 in clockwise direction?

thanks! I always get confused with phenol and toluene...

@slamnxgirlxjulie for visual purposes (when you have the Methyl group coming out from the left side of the ring or whatever its attached to.Its just a way of writing so we show that it's attached to the CARBON like: ----CH3 , if we write it CH3---- , then it would be like you're saying it's attached to a Hydrogen instead.So H3C--- its visually correct. I used to get confused when the semester started so I asked my instructor. :) , good luck!

There are few examples where we use methylbenzene instead of Toluene... A bit confused! Please answer

Amazing channel

What app do you use to draw these?

Another great video

Is there a trend of which to be named first

Does aniline also have a lone pair of electrons?

thank you!!!!!!!!!!

Thanks :D

7:12 the benze refers to benzene plus that c. the ring only is phenyl group

thanks ☻

@drrojas thanks :)

good work

@slamnxgirlxjulie well yes...it's discussed in the video called "Naming Benzene Derivatives Introduction"

You'd always put the '1' first. which ever you decide is on carbon-1 comes first.

I didn't google this, I kind of came up with this, so is benzene cyclohex-1,3,5(or 2,4,6)-triene ? Correct me if I'm wrong

@ASandwichNinja

10 жыл бұрын

You're idea would be correct if there were double bonds between two distinctive carbons, but as he explains in the video, the pi bonds that form the second bond just form as a ring above and below each atom in the ring, giving the ring a much higher stability. This produces a ring with three pairs of electrons able to move freely above and below each atom in the compound, and due to there only being 3 pairs shared over 6 atoms, means each carbon forms kind of 1 and a half bonds with another carbon. This means that you can't technically name Benzene in IUPAC terms, so unfortunately you would be wrong.

No mention of ortho-, meta-, and para-?

is a phenol a example pf a derivative?

why not talk about the O/M/P convention?? I was expecting it, alot

2:28, shouldn't it be phenyl group with a halide functional group?

@justinmann4702

7 жыл бұрын

No. With halogens, benzene is the parent when they halogen is bound directly to the ring. If you were to have a halide (Cl for example) that was bound to a single additional carbon off the ring, then the halide becomes the parent. So, the new name would be Benzyl chloride.

@sanjainarwani44 your not the teachers kid by any chance lol..... this videos amazing

I'd take Sal's choice here since I'm pretty sure bromo comes before chloro because of the alphabetical order.

Also when a CH2OH group is bonded to a benzene ring it becomes benzyl alcohol. (The 2 should be suscript)

If there's another substituent on a toluene such as a bromo, it should be bromomethylbenzene, not bromotoluene.

@girlee702

Stephie Garcia Actually, you are incorrect. You always name the parent group as the main focus when possible. So you would end in toluene in this case, and then state wherever the bromo was at. o-bromotoluene, meaning bromo is in the ortho position from toluene (where the methyl sticks off). Also, 2-bromotoluene means the same thing, Bromo is in the number 2 position, based on Toluene(where the methyl sticks off) being in the number 1 position. I hope that helps.

+Jessica Vegas that's what I thought too. For some reason, in my Pearson O Chem book it says you have to name it methylbenzene instead of toluene. It uses parent names for everything else but not toluene for whatever reason. It teaches us toluene but tells us not to use it for disubstitued benzenes

1. So the reason it's called 1-Bromo-2-Chloro benzene is because of alphabetical order, and NOT the MW? 2. What is the name of a benzene ring with a methyl AND hydroxyl group?

@ximelp7268

6 жыл бұрын

1. Yes. IUPAC says to list substituents alphabetically. It doesn't make total sense but that's how it is. 2. As with open-chain hydrocarbons, the hydroxyl group takes the highest priority. Thus, the base name would be Phenol. For example, 3-Methylphenol or m-Methylphenol. Hope this helps!
