This video describes practices identifying common organic functional groups contained in larger molecules, namely approved drugs. Functional groups covered in this video include alcohols, amines, carboxylic acids, amides, alcohols, phenols, ethers, alkyl groups (e.g., methyl and ethyl), benzene rings, and halides.

Great lesson...I got to see the molecular structure of two of my meds.!

[@lilaho4849]

Amazing lesson, I'm struggling in my chemistry class now and you broke it down beautifully! Answering questions that were confusing me between the differenced of the functional group with the double bond.

[@ChemHelpASAP]

So glad to help. Keep at it. Your hard work will pay off.

Oh my gosh thank u soo much. Idk if this is the method my instructor used, i was absent when she taught it so i dont know and we have test tomorrow hope this works and i completely understand your explanations! ❤

Hi! what’s the functional groups of atropine and where can they be found in its chemical structure? @Chem Help ASAP

[@ChemHelpASAP]

Sorry for the slow response. I can't show a picture, but the nitrogen is an amine (a tertiary amine). The OH is an alcohol (a primary alcohol). The two oxygens that are close together are an ester. The six membered ring is a benzene ring. The single carbon coming off the nitrogen is an alkyl group (a methyl group).

[@biancady3162]

Hello! @6:54 why the nitrogen bonded to 3 carbons at the center of the compound not an amine group? Thank you!

[@ChemHelpASAP]

That's a good question. I left it out intentionally. Amines are typically basic -- the lone pair is electron-rich. For that nitrogen, the lone pair is conjugated with the five-membered ring to form a pyrrole (a specific type of aromatic ring). That makes the lone pair unreactive, so that nitrogen does not show the basicity that is characteristic of amines.

[@biancady3162]

@@ChemHelpASAP Thank you! But if ever we face it in exams, should we name it as amine group?

[@ChemHelpASAP]

@@biancady3162 I would follow the lead of your instructor. Maybe the question would ask you to identify a fixed number of functional groups (5?), and you could pick which ones you are most confident about. The three main functional groups with nitrogen in organic chemistry are amines, amides, and nitriles. The special case with the molecule in the video is a bit outside normal expectations for organic 1.

[@lilbanana6159]

thanks man ur the best, btw hv u made any videos for lattice energy bond energy or anything like that

hi! thank you for your very helpful video, i was reading something abt stress, and i got curious abt cortisol's functional groups, can i ask what is in the middle( like the something with h-bonds?) I got confused in determining it, thank you so much!

[@ChemHelpASAP]

If you look at the picture of cortisol on Wikipedia, the top center of cortisol has an OH group. That is an alcohol, which can form hydrogen bonds with other molecules (including receptor proteins) in the body.

[@nana8768]

@@ChemHelpASAP ohh thank you! i also noticed in the middle like there are 3 H in the molecule (is it also a functional group?), in our homework the choices in identifying cortisol's functional groups are- alcohol, aldehyde, alkene and ketone, and i had a hard time identifying the functional group where those 3 H lie in. I just want to ask if my understanding is right and it is aldehyde? (sorry for a lot of questions im really confused and im kind of shy to ask my teacher) thank you so much for your great help!!!! ♥️

[@ChemHelpASAP]

@@nana8768 Everything in a molecule is part of a functional group, but some functional groups are boring, unreactive, and often ignored. Those three Hs are boring, unreactive, and can be ignored. The molecule has two carbonyl groups (C=O). Both are ketones. See this video... kzbin.info/www/bejne/j6mbg2OObc-fh5I

[@reyb.amahan4411]

What are the functional group found in Batrachotoxin and what are the hybridization of bonds (sigma bonds only)

[@reyb.amahan4411]

Or hybridization of bonds

[@ChemHelpASAP]

Without an image, it's hard to answer this question in a helpful way. The molecule has two alcohols, two ethers, an amine, two alkenes, an ester, and an aromatic ring (the five-membered ring with a nitrogen is called a pyrrole). Hybridization of bonds? Do you mean hybridization of atoms? The molecule has too many bonds (and atoms) to describe all of them.

[@pla779]

At 7:00, the ring in which nitrogen atom is present, doesn't it form a functional group like secondary amine as it is connected to two carbon atoms? Please clear it.

[@ChemHelpASAP]

The ring nitrogen is not a simple amine. It looks like an amine, and it fits the description of a secondary amine. That nitrogen, however, is separated from a carbonyl through a double bond. This kind of nitrogen behaves much more like an amide, than an amine. To be technical, one would most likely call this a "vinylogous amide". This kind of group falls outside what you would normally encounter in first or second semester organic chemistry.

thanks for having a print out available

[@ChemHelpASAP]

My pleasure. I'm glad you found it useful.

[@krantikumarlilhare1608]

Thanks I had solved such questions earlier and I was confused between aldehyde alcohol and ketone. Such questions are asked in 11th class in India. But my teacher told me not to consider Alkane as a functional group. Is it a functional group?

[@ChemHelpASAP]

Is an alkane a functional group? I would agree with your teacher. An alkane is the type of molecule you have, not a part or group coming off the molecule. So, ethane is not a functional group. Ethyl is a functional group as ethyl refers to a 2-carbon group (functional group) branching off a larger molecule. So, alkanes are not FGs. Alkyl groups are FGs.

[@bryesguerra509]

what are the functional group found in tolmetin?

[@ChemHelpASAP]

There are multiple functional groups. There is a carboxylic acid (CO2H). In the middle is a ketone (C=O). The six-membered ring is a benzene ring. The five-membered ring is called a pyrrole. There are also two methyl (CH3) groups - one off the benzene ring and another off the nitrogen of the pyrrole.

[@eleechimdiaclinton368]

Carbonyl attached to an OH is called what?

[@ChemHelpASAP]

carboxylic acid

[@pla779]

Secondly, is benzene ring a functional group

[@ChemHelpASAP]

Technically, although many people (including me) might call benzene a function group, it is not. Benzene is a molecule. If a benzene ring is connected to your molecule, you would call that a "phenyl group" or more generally an "aryl group" (an aromatic ring group). This much like methane. Methane is a molecule. If you have a CH3 off a molecule, you might call that a "methyl group" (specific) or an alkyl group (general). Regardless, not many people will say that "benzene group" is incorrect.

[@pla779]

@@ChemHelpASAP can u plz differentiate aryl functional group and phenyl functional group, it often confuses me in mcqs.

[@ChemHelpASAP]

@@pla779 Here is a video that describes how to identify aromatic rings and aryl groups. kzbin.info/www/bejne/eqSxqGBtqM9rotU A phenyl group is an aryl group, but not all aryl groups are phenyl groups.
