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!
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 RUclips. Thanks so much for making it!
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.
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💗
You're really amazing! I like your way of teaching. I have never seen a well explained video on RUclips than yours. Thank you so much for your efforts! 😁
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 ?
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
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.
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.
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"

lifesaver
i dont usually comment, but you have my gratitude
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'?
I think so
Was thinking the same, formyl should be correct
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?
@@muhammadjubair248 formyl
@@koukizsana7135 ok thanks today I'm having organic chemistry final exam and you told me already
You are the real teacher,God richly bless you.
Simple but effective teaching method! Excellent!
You are so gifted! Definitely you are my best on RUclips no doubt
I think you deserve to be a professor! And writing your own books.
The way you explain is so soothing and elaborate...🥰
@6:50 It should be 4-bromo-6-formylhexanoicacid since the aldehyde has "fomyl" prefix.
thats what i was thinking
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.
Correct
There's teaching this one here on youtube, you're unbeatable.
More strength to your elbow

Your video are so helpful. I am so grateful. I practiced through your videos & ace the general chemistry .
even after 7 years, this video still goated af❤
I owe a portion of my first salary to you. THANK YOU SO MUCH !!!
You're really amazing! I like your way of teaching. I have never seen a well explained video on RUclips than yours. Thank you so much for your efforts! 😁
This man is a blessing to this 🌍 earth
It was perfectly taught . Thanks a lot
At 2:52 can we call it hex - 3 - en - al? Sorry if it's dumb.
Yes of course.. We can
I love you sm organic chemistry tutor you da best
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 ?
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
trueeeee
You're superb! & I've admired u as a great Teacher
4-bromo 6-formyl hexanoic acid
6:50
No it's 3 bromo-6 formyl hexanoic acid since left side compund is aldehyde as well and bromo group is closer to it 😀
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
What's the difference between oxo and formyl? Can you please enlighten me?
@@Apollo-wg1mc we use oxo for ketones and formyl with aldehydes this is what teacher told us in the lesson
Doing a unit in Fundamentals of Carbonyl Compounds and Amines and this is very helpful...you get a solid 10/10.
The molucule at 2:49 should be trans-3-hexenal or trans-hex-3-enal
Thank you for this amazing video❤
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
The hexanoic acid is the main chain
And has a priority over the aldehyde
@@bluekaiser9452 thanks hey my bad. Must have been tired from studying
Thanks sir
I like your teaching method
its 1 am and i have a final tomorrow
why in 8:36 is phenyl? that should not be a toluene?
dude toluene is a molecule, phenyl its a group, may have the same thing or very close, but they aren't the same
Actually at 6:53 it should be formyl or oxo
Yes it has to be formyl as it is an aldehyde as a substitute not ketone!!
What is he does he mean at 2:16? I really don't understand it, i'm in 8th grade and i really don't get it..
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 ?
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.
At 2:14 can I just say 4- methyl -1-pentanal ? Is it wrong?
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.
@@niiinooon1702 wow.. since you know alot about organic chemistry.
Thank you for the video! well explained
Thank you for such helpful videos. :-)
Did you mix up the substituent names between aldehydes and ketones? I'm more confused now.
I know its late but yes he did.
He didn't. Both oxo and formyl are the prefixes.
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.
This is just a common name from benzene derivatives
Thanks for this. I hope the nomenclature rules have not changed much.
Thank you is such a small word to express my gratitude….but still thanks alot
Good explanation
Teacher
awesome explanation
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.
What do we call when two benzene rings are attached as a substitute?
n,n-diphenyl
why is the aldehyde oxo? 6:52
When aldehyde is used as a substitute the term is -oxo
Some literature refers to an aldehyde substituent as -formyl.
I think he made a mistake, ketone substituent name is -oxo, aldehyde substituent name is formyl
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
@@taniaax33 oxo is for ketone, its formyl for aldehyde
Great one mate 👍
Totally different, thanks alot !
Why don't you use E/Z in your naming?
Nora Ross ya I think that he forgot
You are highly intelligent wow
You are 100% better
Great video
What does the R represent on the structure though ?
Do u have the updated version this was 6 years ago. Doesnt iupac update every 3 or so yearssss
Hello, how can I find a chart online to provide the naming scheme based on the amount of carbons ? Anyone ?
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
Thank you so much 😊
10:35 timestamp
thank you soooo much sir!!!!!!!
don't you need to name the cis/trans-configuration in the fourth example?
How do you keep all these things pleaase!
Does alcohol have a higher priority or aldehydes?
aldehydes but you name the alchohol first
anybody else immature enough to laugh every time an alkane aldehyde is named?
This man has made so many Doctors and Engineers. Incredible lmaooo
How do you name if there are two aldehydes attached?
exapmle: hexanedial
u keep E in hexane and add "di" for double
Tnqq somuchh💖💖💖
Thaaaaanks a lot 😍
Why is it -6-oxo when it is an aldehyde and not ketone
at 3:31 isn't that OCH3 a methoxy, not an ether?
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"
Hello
Thank you 😊
I thought u should count the carbon from first dot not the second?
Thank you
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...
I couldn't know the differences between benzyl and phenyl
