thanks so much oh my goodness. Science deploma is tmro and I've watched so many of ur vids to brush up on stuff we learend, plus learned some tips from you too. Ur a life saver, thanks so much
Anytime we have a cyclic carbon chain, we only name within that one, unless we have a phenyl side group in a benzene molecule in which the carbon away from that molecule gets precedence.
@@banaagedwin1806 Oxo- is used if the aldehyde terminates the longest chain of carbons (assuming there is a higher priority group like a carboxylic acid). Formyl- is used if the aldehyde does not terminate the longest carbon chain but is merely a "side branch" on the chain. Basically, if you count the aldehyde's carbon in the longest chain, it's an oxo-.
Because don't forget about the c=o part, we always count the c when naming right? As you can see, the carbonyl group is outside the cyclohexane so that's why we call it cyclohexane carboxylic acid
Could you help me figure out what you would call a certain plant phenol from magnolia called Honokiol or, ((3’,5-di-(2-propenyl)-1,1’-biphenyl-2,2’-diol); (hypothetical) converted to phenolate salt using sodium carbonate, then neutralized pH with hcl? would there be a side reaction induced by the CO2 gas released from the hcl/sodium carbonate neutralization significant enough to convert it to carboxylic acid salt? Just wondering idk if I have this right but trying to learn.
Alan O'Hara when functional group is directly attached to the ring, we use special name of the functional group in the nomenclature. Here are some of them- Aldehyde-carbaldehyde Acid-carboxylic acid Amide-carboxamide Cyanide-carbonitrile Ester-carboxylate Acid halide-carbonyl halide
You confused CH3 with substituent, despite it being a part of a chain. Thus, a chain consisting of 4 carbons corresponds to butane. Cis and Trans can only be used for alkenes with same substituents. First butenoic acid on the left has two different substituents, CH3 and COOH, therefore you must use E and Z isomerism. E(entregen or smth) is equivalent of trans, while Z(zuzzamen, translates to "together") is used for Cis accordingly.
I quite not understand the last compound you name, shouldn't you indicate the positions of the carboxylic acid , I think it should be hexane-1,6-dioic acid right
I really hope someone can answer this: How can we name it if the carboxylic group is not on the end of the longest chain like when it is placed in the middle?
A carboxylic acid group is always on the end. If you're thinking of a C=O group in the middle of the longest carbon chain, that would be called a ketone. A carboxylic acid has the carbonyl (C=O) group bonded to one --OH and one organic substituent. A ketone has the carbonyl bonded to two organic substituents. Ketones are named with the suffix -one on the base name and a number indicating where the carbonyl group is (e.g., 3-hexanone).
They use formyl- if they are not part of the longest chain containing a higher priority group. Otherwise they use oxo-. Basically, it's oxo- if it terminates the longest carbon chain, formyl- if it doesn't.
If you do that you are leaving ambiguity about what's at position 3. It's like Pent-3-en-1-oic acid. Wouldn't use that form, but just showing what it would equate to.

Fast and acurate explanation including a lot of examples. Love it.
Oxo is for ketone

youre kind of amazing.. thank you so much
AMAZINGLY clear explanations that help me feel less like an idiot - thank you so much for your help!
The best explanation ever💌💌 love from Pakistan 🇵🇰 A big thank you..💖
yes.....I m from india.

Nice interface. My eyes are not get tired faster
Your explanations are The best . Thanks a lot for uploading this video
thank you so much for the video its the best one out there i was really confused with this chapter im feeling more confident now thanks to your videos
Out here saving lives
Very good explanation 👌love from India ❤️
I was able to understand so much after this video! very great and to the point!
Amazing video. You are my savior
7:39 why didn't you begin numbering at the carbon that is within the carboxylic acid group??
Anytime we have a cyclic carbon chain, we only name within that one, unless we have a phenyl side group in a benzene molecule in which the carbon away from that molecule gets precedence.
Not sure if the correction has been addressed, but @6:08, shouldn't the name of the compound be 4-amino-7-ethoxy formyl octanoic acid?
Aldehydes and ketones are represented by the suffix -oxo-
Formyl is also a formal name of an acyl group with one carbon
Thank youu for your efforts👍🏻
is it wrong to have space between cyclohexane and carboxylic acid at 6:48?
God bless you
God will prosper you and your family😭😭🙏🏼🙏🏼🙏🏼❤❤❤
Thank you very much. Your videos are really helpful
thank you sir;it was really helpful.
i genuinely love you💌💌💌💌💌💌
You are my saviour
8:51 Is there supposed to be a capital letter and space there?
From Somalia thanks teacher
love your videos
Oxo is for the ketone substituent and formyl is for the aldheyde substituent....right ???
Both are oxo
both are true
I also notice it, can someone explain thank you
@@banaagedwin1806 Oxo- is used if the aldehyde terminates the longest chain of carbons (assuming there is a higher priority group like a carboxylic acid).

Oxo used for both aldehyde and ketones if they are alphatic
In aromatic oxo for ketones and formyl for aldehyde
I love this man
Thanks for existing mate.
6:06 aldehyd substitution oxo ????
it should be -8-formyl, formyl is a substituent in a chain for aldehydes
It can be oxo or formyl, just either of the two
it was really helpful .thank you
Thank you once again.
Love you man
awesome video
6:35 why is it not called cyclohexanoic acid?
Because don't forget about the c=o part, we always count the c when naming right? As you can see, the carbonyl group is outside the cyclohexane so that's why we call it cyclohexane carboxylic acid
Was there any video made about this topic prior to this?
very helpful for self-study
1:38, what if, in the end of carbon 5 has a CH3?
Like for real thnks🥰,,,understood evrythng basically
Why don't we name it cyclohexyl methanoic acid ?
Since it looks like a substituent 6:45
12:08 please I don’t understand how methyl got to the naming, cuz I can only see ethyl as a substituent, but methyl is not a substituent there??
The ch3 in the second carbon
thank you so much ❤️❤️❤️❤️❤️❤️❤️
does the E and Z the same with trans and cis
Yep
6:08 but my teacher said when aldhyde act as lower priority the suffix is "Formyl" While oxo only apply on ketone. Can anyone explain?
yes i am confused too
Same, that's why I came in comment section, seeing you commented 3 months ago; is your confusion clear now ?
yes.. there can be either 'formyl' or 'aldo'
Could you help me figure out what you would call a certain plant phenol from magnolia called Honokiol or, ((3’,5-di-(2-propenyl)-1,1’-biphenyl-2,2’-diol); (hypothetical) converted to phenolate salt using sodium carbonate, then neutralized pH with hcl? would there be a side reaction induced by the CO2 gas released from the hcl/sodium carbonate neutralization significant enough to convert it to carboxylic acid salt?

Thankyou very much sir
It helped alot
You are the best
Thank you so much
Great thank you sir
thank you
U R great.
6:48 why isn't it cyclohexanoic acid?
Alan O'Hara when functional group is directly attached to the ring, we use special name of the functional group in the nomenclature.
Here are some of them-
Aldehyde-carbaldehyde
Acid-carboxylic acid
Amide-carboxamide
Cyanide-carbonitrile
Ester-carboxylate
Acid halide-carbonyl halide
3:20 i can't understand it
thanks!
Why in the three example named as (E)-2- butanoic not as 4-methyl butanoic acid or as trans!?
You confused CH3 with substituent, despite it being a part of a chain. Thus, a chain consisting of 4 carbons corresponds to butane.
Cis and Trans can only be used for alkenes with same substituents. First butenoic acid on the left has two different substituents, CH3 and COOH, therefore you must use E and Z isomerism.
E(entregen or smth) is equivalent of trans, while Z(zuzzamen, translates to "together") is used for Cis accordingly.
3:02 why use (E) in name 🧐
I quite not understand the last compound you name, shouldn't you indicate the positions of the carboxylic acid , I think it should be hexane-1,6-dioic acid right
thanks sir
❤
Quick q , when do we remove the 'e' when naming for example pentane to pentan?
I guess it sounds better
and simpler pentanoic than pentane oic
Nice
in last example 2_methyl 3 ethyl is not possible????
I was expecting ethoxy and methoxy actually
9:29 ETHERRRRRRR
thanks :)

How to name compounds with three carboxylic acid groups attached to a carbon chain?
My brain hurts haha I hate chemistry with a passion but of course I have to take it for nursing
What am i suppose to do when there are more that one double or triple bond??? Anyooone?
I named the last one as using xy i.e ethoxy, methoxy
Why is it ethyl and methyl
can benzoic acid be also named as benzene carboxylic acid? Why is it so?
I know this is an old comment but that was exactly what I was thinking. My CHM professor says benzoic acid. May mean the same thing.
What if there are only 3 carbons?
i love you
عسل عسل ماشاء الله 😔💜
Why do we use E and Z instead of cis and trans ? Please reply anyone
Cis and trans aren’t always applicable, E and Z are.
dont aldehydes use formyl instead of oxo????
They use formyl- if they are not part of the longest chain containing a higher priority group. Otherwise they use oxo-.
Basically, it's oxo- if it terminates the longest carbon chain, formyl- if it doesn't.
correction at 1:42 possibly? (E-3) Pentoic Acid. I was taught to drop the (e) and add(oic)
If you do that you are leaving ambiguity about what's at position 3. It's like Pent-3-en-1-oic acid. Wouldn't use that form, but just showing what it would equate to.
please upload a video about Carboxylic Acid and nitriles
0:21 Carboxylic acid can’t be called CO2H because there is no bonding between O-atom.
Gggyyy
Ethoxy should be numbered first then amino, right??
Wrong.......
According to alphabet (a) comes first so amino comes first then ethoxy.
How can butanoic acid form there are only 2 carbons
i love your other videos but this is hard.i cant understand
oxo is the substituent name for ketones, not aldehydes, it;s supposed to be methanoyl?
You're right!
no no dude it is oxo and formyl for aldehyde it shares oxo same with ketone but it right.
Ketone and aldehyde are organic compounds that incorporate carbonyl functional group which implies to the substituent of both
