[@tyleralger6083]

I just want to say, you have a real gift. It is very rare to find someone who is not only very intelligent but also articulate enough to teach others. In my opinion that's the mark of true intelligence! You have no idea how many students you've helped. You're making a huge difference! I've used your videos for both general chemistry classes, both physics classes, the first part of organic chemistry and now for the second part of organic chemistry. You've been extremely helpful in all of these! Thank you so much!

[@M.kenny365]

This was an awesome explanation and review of the relevant nomenclature! I really appreciate how you covered so many examples in the span of 12 minutes. This channel is such a gem among everything else on KZbin. Thanks so much for making it!

[@hafeatahir]

lifesaver i dont usually comment, but you have my gratitude

[@hartleychristain]

You are so gifted! Definitely you are my best on KZbin no doubt I think you deserve to be a professor! And writing your own books.

[@rechogaming6438]

Thank you so much po talaga kase every time na nahihirapan ako sa biochemistry, lalo na dito sa naming, and identifying what type of carbons is, napapaintindi niyo po samin ng maayos, at parang ang Dali lang pag ikaw yung nag didiscuss again thank you so much💗

[@jieunlee2870]

in 6:53 i think it's not an 'oxo' because it's not a ketone subs. but it's a aldehyde subs. so it should be a 'formyl'?

[@汤佳璇-z1j]

I think so

[@ShiNiGaMi-bb2ep]

Was thinking the same, formyl should be correct

[@muhammadjubair248]

Can anyone tell me it should be oxo or formyl some told me it's oxo some told me it's formyl so which one is the correct one?

[@koukizsana7135]

4-bromo 6-formyl hexanoic acid

[@muiz4444]

6:50

[@ahmedrazaabbasi5998]

No it's 3 bromo-6 formyl hexanoic acid since left side compund is aldehyde as well and bromo group is closer to it 😀

[@ArtinTheBeast]

Ahmed raza Abbasi correct me if I’m wrong, but the group with the highest priority always starts at 1. Therefore, it’s not 3-brink but 4-bromo

[@Apollo-wg1mc]

What's the difference between oxo and formyl? Can you please enlighten me?

[@koukizsana7135]

@@Apollo-wg1mc we use oxo for ketones and formyl with aldehydes this is what teacher told us in the lesson

[@staycalm9979]

@6:50 It should be 4-bromo-6-formylhexanoicacid since the aldehyde has "fomyl" prefix.

[@wajdy2620]

thats what i was thinking

[@Sprite-od4xl]

No, because the carbonyl carbon of the aldehyde group is counted in the main chain so aldehyde is not a substitute. But only =O(oxo) is the substitute. So he is correct.

[@Vaishnavi1]

Correct

[@indiasbeauti4533]

Thanks sir I like your teaching method

[@lascarro87]

Seriously , greatest video on the web ! - why is the benzaldehyde not named with “carb” before the aldehyde ? As for the cyclopentane carbaldehyde before it ? That would be the last two naming in this video.

[@mattflores8911]

This is just a common name from benzene derivatives

[@amirakardas5757]

Thanks for this. I hope the nomenclature rules have not changed much.

[@shakiba7860]

Thank you for the video! well explained

[@arthasmenethil-ww6uu]

anybody else immature enough to laugh every time an alkane aldehyde is named?

[@ayushijain8671]

Thank you for such helpful videos. :-)

[@NM-nk9mf]

There's a confusion.! Why in the last 2-3 examples numbering was not started from carbon having the oxygen , but from its neighbouring carbon ?

[@rwayle]

Aldehydes can't be directly bonded to a ring, so you can sort of think of the ring as a substituent of the aldehyde. The carbon of the ring that is bonded to the aldehyde is carbon#1 OF the ring.

[@yusra7485]

Totally different, thanks alot !

[@zoop34]

The molucule at 2:49 should be trans-3-hexenal or trans-hex-3-enal

[@aishachaudhary5128]

Great video

[@ramiroarias6407]

i thought when aldehydes were substituents they were called formyls or something and i thought oxo was purely just for ketones? is it wrong to put 6-formyl instead of 6-oxo at 6:38 ?

[@drkd7207]

At 2:52 can we call it hex - 3 - en - al? Sorry if it's dumb.

[@Noctbee31]

Yes of course.. We can

[@abhisheka1775]

Great one mate 👍

[@gabrielogwuche7085]

Thank you so much 😊

[@Hii_nataa]

in the example 6:53 the substituent 6 oxo is an aldehyde right? but the prefix of aldehyde is formyl? and oxo is prefix is ketone? it does have H it must be an aldehyde? 4-bromo-6formylhexanoic acid? help😭 I'm lost

[@opseiee]

trueeeee

[@MrK-tb9qi]

6:52 i numbered it the other way round because its 3-bromo-1-oxohexanoic acid. I'm conflicted as to why you chose 4-bromo-6-oxihexanoic acid

[@bluekaiser9452]

The hexanoic acid is the main chain And has a priority over the aldehyde

[@MrK-tb9qi]

@@bluekaiser9452 thanks hey my bad. Must have been tired from studying

[@blissfuliska9866]

thank you soooo much sir!!!!!!!

[@noraross5696]

Why don't you use E/Z in your naming?

[@dinkleberrylongbottom5175]

Nora Ross ya I think that he forgot

[@muhammadjubair248]

Actually at 6:53 it should be formyl or oxo

[@bintsiraj5858]

Yes it has to be formyl as it is an aldehyde as a substitute not ketone!!

Did you mix up the substituent names between aldehydes and ketones? I'm more confused now.

I know its late but yes he did.

[@adriyaevans]

He didn't. Both oxo and formyl are the prefixes.

Yes bro

Why is it -6-oxo when it is an aldehyde and not ketone

10:35 timestamp

[@Messi5530]

I think you got the order of priority wrong for ethers there my guy... they're nearly at the bottom of the priority list of organic groups...

[@cieraterry1680]

Is the last problem suppose to be 4-chloro-3 methyl cyclohexene carbaldehyde? I thought benzyl needed to have a CH2 attached to the benzene ring.

[@bfggbhgxcnkhf]

don't you need to name the cis/trans-configuration in the fourth example?

[@tamannapanda4219]

[@bintsiraj5858]

What do we call when two benzene rings are attached as a substitute?

[@johnlestergino8645]

n,n-diphenyl

[@es9md]

I couldn't know the differences between benzyl and phenyl

[@bestk7]

❤❤❤❤❤

[@JesusRamos-wh4zy]

why in 8:36 is phenyl? that should not be a toluene?

[@christopherfigueroa3083]

dude toluene is a molecule, phenyl its a group, may have the same thing or very close, but they aren't the same

[@Shmirtz]

What does the R represent on the structure though ?

I thought u should count the carbon from first dot not the second?

[@raizel2357]

exapmle: hexanedial u keep E in hexane and add "di" for double

[@pavitrajaya4568]

At 2:14 can I just say 4- methyl -1-pentanal ? Is it wrong?

[@niiinooon1702]

You don't need to put 1-pentanal since its already known that the first carbon is where the aldhyde is attached. So 4-methylpentanal is correct.

[@hartleychristain]

@@niiinooon1702 wow.. since you know alot about organic chemistry.

[@reamduke26]

Hello, how can I find a chart online to provide the naming scheme based on the amount of carbons ? Anyone ?

[@jaktheduk9042]

may be a little late.. but just a flex: 1 carbon- Meth 2 carbon- Eth 3- pro 4- but 5- pent 6-hex 7- hept 8- oct 9- non 10- dec

[@JS-vo6go]

why is the aldehyde oxo? 6:52

[@taniaax33]

When aldehyde is used as a substitute the term is -oxo

[@TheOriginalArchivist]

Some literature refers to an aldehyde substituent as -formyl.

[@richardbarros8187]

I think he made a mistake, ketone substituent name is -oxo, aldehyde substituent name is formyl

[@cillanichole]

Richard Barros yes! I was just thinking that. I had to pause and look at the comments because I learned that aldehyde as a substituent is formyl

[@bintsiraj5858]

@@taniaax33 oxo is for ketone, its formyl for aldehyde

[@theamazingpotatocc7580]

methoxy

[@moncayoyuri4600]

Plss do a condensed

[@pleb5309]

0:52 bad joke tho

[@Bakedbread69]

at 3:31 isn't that OCH3 a methoxy, not an ether?

[@ayhamyahya6939]

It is an ether group, but since it is written as a substituent(because it has less priority than the other functional groups in the chain), it will be written as methoxy, ethoxy, etc. Same goes with OH group. It is an alcohol but if more important functional groups are present, then it be written as a substituent with the name "hydroxy"
