So in h3o+ hydrogen is partial positive?
Thank you so much dude. If I ever get anywhere far in life I hope you know that it’s because of you. And I hope I can become like you someday.
My entire degree is in your hands! 🥺🔥❤
This dude just makes sense man. Thank you for you contribution to society
Wow, that oxygen in the last example at the end of the ring was such a greedy bastard that it saw the positive formal charge on the carbon like 4 bonds away from it and literally just WENT for it. Like dude, chill.
lol...right
You are a good man who contributes to the dissemination of science. I respect you and appreciate you. I am a Muslim.
Is it necessary to say your religion?🤔🤔🤔
@@unhuman537 lmao i am muslim too but that was kinda weird
best orgo chem videos I could find, thanks.
Thank you so much for making it so simple ❤
Your channel is life savour
nice..really so clear...
This video was very acidic, and by that, I mean that it was spicy! Thanks for sharing all of this great knowledge!
3:37 Does anyone else here him saying "produc"? Still love you The Organic Chemistry Tutor
*hear. Cheers!
Wait, what happens to the initial molecule after it takes the H away from the ring? Does oxygen become positive? If so, what happens next?
I mean, when it’s used as a base...
19:07 Wouldn't the whole reaction be different if water was the base in the first place? Because it would attack the carbocation and make it something completely different.
Did you find out the solution to this or is it just “partialy negative oxygen reacts better”?
What happens to the Hydrogen after the first step?
at 14:11, why wouldn't there be a hydride shift? Why would the ring expand instead?
Because forming a six membered ring via ring expansion brings more stability than forming a tertiary carbocation. The stability order of cyclo compounds- 6>5>7>4>3 and in each case a ring expansion would be favoured rather than shifting the plus charge
You are life saver
In last example why didnt H+ attack on oxygens lone pair ?
🙏🏼 thank you!
9:19
Shouldn't the hyperconjugation be dominating at that point of time..
As the 2° carbocation you formed was having less hyper conjugated hydrogens, and also shouldn't we look for the stability at that point of time rather than what we are getting afterwords.......
PLEASE EXPLAIN 👆👆
Same doubt
Sir in the last qs, 4 stereoisomers will be possible as there is 2 chiral carbon...plz check
In the second step when H2O is added why isn't there a breaking of a H from the H2O and what happened to the H that was moved onto the molecule in the first step?
That's my question also
thanks a lot
amazing
On 14:05, do I need to make a 6 carbon ring or can I stick with it being 5?
18:02 that carbon 6 does not exist actually, it was the -OH.
How to know whether the carbon has hydrogen on it??
what is the concept called where you took the alkene and changed it to a ring and vice versa
@Harish Sridhar actually, I would say it's up to 6. if you go up to 7 you d have to collapse the ring back to 6. Cyclohexane has perfect angles. Almost no strain, zero heat of combustion. Notice organic chem is mostly about cyclohexane and aromatic, phenyl rings. All 6 angles.
@@Edboyproduction1 yes I completely agree
@@Brad-qw1te IIRC, 6-membered carbon rings have bond angles of 109.5 degrees, and there isn’t any ring strain. The rings don’t have to be perfectly planar; there are “boat” and “chair” configurations.
@@Edboyproduction1 Cyclohexane has a heat of combustion of over 3.9 kJ/mol. Even though there isn’t any ring strain, the carbon can still be oxidized all the way to CO2.
en.m.wikipedia.org/wiki/Cyclohexane_(data_page)#Thermodynamic_properties
It's called Ring expansion or Contraction (in 7 or more membered rings)
At 10:00 why isn't there any rearrrangement with the first product
is it me or are the double bonds on the last two examples not drawn on the molecule?
Are you blue color-blind? lol
What if h3o+ reacted with these?
19:30 does anyone know how to name what is in the right top corner?
2,2-dimethyltetrahydrofuran
Maja aa gya
I love you
So guys u saw in the video sir clearly said that when the students request for new chapters,sir start feeling the pressure.so pls don't request sir for new chapters cuz he gets under pressure and misses few topics.yaar koi insaan free mein itni badhiya phy aur chem padha raha h usko padhane do uske tarike se.
