thank you god for sending this person to teach us
I currently have an A+ in organic chem thanks to you. Honestly, I know enjoy chem because of your videos. I used to sooooo hate chemistry. Thank you very much for your efforts and help.
I'm glad you found my videos useful. Thanks Laila
@@TheOrganicChemistryTutor one of the best organic teachers , deserves more subs and views
I got an A in organic chem through your videos 🙏 thanks
@@Anonymous-vo8ksnot one of the best, he is already the best among all
Your amazing man, ever since I started watching your videos, you have inspired me to go on and pursue chemistry. Currently in my 2nd year and whenever someone complains about chem or organic I direct them to you! Thanks a ton!
You're very welcome
The examples are really awesome. It has covered almost all possible namings of ketone. Great work.
I really don't think that I'll be able to pass AS chemistry if it wasn't for your videos!! Thank you so much!! Chemistry is like wayyyy more fun with youuu!
You know there're still good people when you see someone like him
Good explanation. Thanks for your efforts. Also I have shared this video with a high school student who will be having a text very soon. New York City schools are having online classes because of the COVID-19 pandemic, but some of the instruction lacks needed details. This video has helped to fill some of the gaps. Thank you again.
I got an uno for org chem because of your videos! Thank you so so so much.
I’m medical student from Iraq 🇮🇶 I’m really in love with your explanation
your videos are so useful & interesting for me ☘️🌹
Thank you so much 🤍🙏🏻🌸
You’re really Talented 👍🏻🌸
Me too
YOU ARE JUST A LIFE SAVERRR, I'VE BEEN STRUGGLING WITH CHEMISTRY BUT I REALLY ENJOY WATCHING YOUR VIDEOS. THANK YOU SO MUCHHHHH!! (I have exam today and I'll be back after hehe)
Thank you so much,organic chemistry has never been this fun.
Really right
This guy answer my question just right at the beginning of it
honestly you are just so good.. we totally appreciate what you do
Man don’t die in organic chemistry… your so helpful brou
i dont get it
Thank youuuu for teaching in such an understandable manner!
I truly thank God for u organic tutor my God open more doors in your life and more wisdom
Thank you so much, i'm indonesian people, but i understand you more than my teacher ✨
Thank you so much sir for these types of video.....I watch your all organic lecture... ☺️
The best I have watched this year
Perfection 🤸♂️🤸♂️🤸♂️ this is very interesting as compared to a three-hour lecture that don't make sense
I got organic chemistry 1 A ..thank you so much am also hoping to get A organic 2 and still watching your vedios thank yu
Thank you for keeping these free!
Learned a lot in less than 15 min.....thanx!
Thank you so much sir for such a tremendous explaination
idk why instructors cant explain like this.....smh they just speak 1-2 hr speaking nonsense
Exactly, just listen to the instructor until he mentions the topic, then search that topic on this guy's channel...
@@jeffreyhuang3814 lol thats exactly what i did
once he mentioned the topic i picked up my shit nd got the hell out of the class
Yes literally!!
true AF
I don't listen in college lectures.. But here it seems interesting while listening😅
BRO U THE GOAT KEEP DOING CONTENTS
Thank you so much for this amazing video 🧡🧡
THANK YOU.. U ARE SAVING MY LIFE!
I never fail oragnic chemistry because of u
I love how its propanone, but chemists were like "nah, dawg, we gonna name you acetone, just because"
You're very amazing! U're the best.🤩🙏
We're going to have a long test on Monday haha 😂 thank u so much I learned a lot from you than my teacher(tbh) 😭
Very amazing!
Great work 🎉
This was really helpfull brother
thank you very much sir you tough me how to enjoy organic chemistry
you’re the best thank you so much
Thank you so much you are the best ♥️♥️♥️💯
Thank you so much, Sir. God bless you!
This video is amazing
I think there's a mistake in the 2-cyclopenteneone. Isn't it supposed to be 2-cyclopentenone?🤔
same thought
When I checked it, the original suggestion was correct for nomenclature --> 2-cyclopentenone
Isn’t it obvious? That he has made a spelling mistake? YOU GUYSSS 🤭🤭🤦♂️🤦♂️🤦♂️🤦♂️
Thank you so much for this video ...
Anytime
thank you soooooooooo much for explaining!!!!!
What a god.
Thanks a lot . U’re solid
thankyou it has being of great help
I just listened to an hour-long lecture without understanding anything, and he could have done it with 13 minutes.!!
this is wild, I better be making grade A you know what after my 1000th hour of replay.
Am i the only one who comes here for his voice only 😭
5-bromo-2-methoxy-3-hexanone
great work sir.
Amazing explanation
Many thanks!❤
Can we call 5-xoxHexanal as 1.aldehyde - 5.Ketone- Hexyne?
the carboxylic acid part kind of came out of nowhere on this one 6:10
Thank you 🙏
Thank you so much
i love you teach
Thank you
how do you understand which one has more priority in which case? as in you mentioned ‘in this particular reaction’ so i am guessing it varies from formula to formula?
You can watch a particular video on "Priority of different functional groups" or may I tell u ??
thank you.
Ok can i just say omg his voice was like🥵🥵
Thank you is not enough
thank you sooo much
nice video thnk u so mch
How do w know which functional group has more priority?
Here is the arrangement of their priorities from highest to lowest:
1. Carboxylic acid
2. Esters
3. Amide
4. Aldehyde
5. Ketone
6. Amine
7. Alkyne
8. Alkene
9. Alkane
How to differentiate carboxylic acid and alcohol of they both use OH?
A carboxylic acid group is always COOH while alcohol is simply OH so if there's an alcohol attached, it is only C bonded to OH without the double bond to O on the same C
A carboxylic acid has a carbonyl group which is an oxygen atom that is double bonded to a carbon. Carboxylic acids can only be found at the ends of an organic compound which is different from alcohols since they can be present in any of the carbons in the longest chain of a compund.
Thank you!!!
please answer me 🌸
it's correct to say
(( 2-cyclopentene -1-one ))
or as you said
(( 2-cyclopentenone ))
I think the 1 is not necessary to put.
You have to ommit 1 coz its already understood
its correct but unecessary u can ommit the 1
Still if you put 1 in the name, that should be 2-cyclopenten-1-one since no vowels should be following each other. You can also name it as cyclopent-2-en-1-one. But as always said, 1 is optional in cyclic chains unless there are more than one of that specific functional group, where you should always indicate their carbon numbers.
5-bromoheptan-2-one works? 4:20
Thanks
If it is aromatic ketone than what can we do...??
Tqu sir🙏🙏
i know no one’s going to answer this until it’s of no use to me but i’m confused.
the structure at 10:37 was said to have a alcohol (the OH at 3). i thought alcohol was only allowed at the end of the chain? or is that only carboxylic acid. even so, why was the name hydroxy?? isn’t it 3-methol? isn’t the IUPAC suffix for alcohol “ol”?
where did hydroxy come from ??
i looked it up and it’s a hydroxy substituent. can they be used interchangeably? is it the same thing?
I've never heard about methol,
I thought hydroxyl fg is more priority than ketone
I thought it would be 2-oxo-pentan-3-ol
Can i write 2-Butanol as butan-2-ol
Yes correct
iirc names like butan-2-ol follow the more modern naming convention whereas 2-butanol is the "old way" that is still used pretty often. Both are correct
Error at 10:10 it's not 2-cyclopenteneone but 2-cyclopentenone
No😂
It has alkene fg ,so we must put "ene"
Organic chemisty is sooo damn hard 😩
just have a positive attitude and it will be ok
Excuse me sir but ketone can't come at first position right? So why we name co group as 1 in cyclo haxane
They can be at carbon 1 if it’s a ring or if position 1 is bonded to something like a phenyl ring (1-phenylpropan-1-one)
👌👌
At the time stamp at 10:01 isnt't the structure supposed to be name 2-cyclopentenone
Because it has alkene group function
I thaught the thumbnail was nanami kento :'D
why in the first exercise you didnt mention where the ketone is?
Explain with some clear voice
❤️
I thought amides have more priorrity than ketones idk someone help
Yes amide has more priority than amine
There’s no amide in this video, amines have less priority than ketones. Make sure you’re identifying the groups properly
I know this is really late but an amide is a carboxylic acid derivative, which means the hydroxy group (OH) in carboxylic acid is replaced by an amino group (N). Which is why this NH2 in the video is just an amine, not amide.
2-cyclopenteneone is wrong 2-cyclopentenone is correct
For the last one, can it also be octan-2-one? @TheOrganicChemistryTutor
Yes, that's the modern way.
5-oxohexanal ka structure glt hai
You're doing it wrong my dear
You have no idea what is going on😁
I Pray earnestly sir, may God REVEAL to you his purpose and will for you, in JESUS NAME. AMEN. I GAINED ALOT
💃💃💃
1st is not propanone it is propan-2-one
im cooked
ngomong ape dah lu
lol...he always says "thats it for this example" before the last example as if to say thats it for this video in the end.see 12:37 and 13:22
Are u married ?
why are you so good 🫶
Thank you so much
Thanks
