Good
Congratulations sir,I have understood well
Welcome
thank you so much very helpful
Welcome
How to balance an equation
Coming soon
❤
I am from Bangladesh, where are you from?
Nigerian
Nice one 👍👍
Not aromatic
That's one atom of chlorine 😢not 2 as you said sir.
❤
Thanks a lot
Thanks so much Sir
thank you very much sir 🙏🙏
Welcome
BOMBOCLAAAT THANK YOU BROTHAA
How many shared pair of electrons are in ammonia?
Three pairs of electrons. A total of six electrons shared ammonia.
Think about quetion number 2 again.
Great job dont give up work hard u will get succesfull
🎉awesome
Not aromatic it is not completely conjugated
Sir catalyst thanks alot
Welcome
Can you tell me plz how can we know which of the compound share large electron
I don't understand your question
Come to my WhatsApp
The compound is not in aromatic nature Since it gave 1.5
The video was so Short 😢
Thank you so much
❤❤❤🎉
Why post this?
Thanks sir 😊
This is the first time am really composition of an organic compounf and it's all thanks to you
To God be the glory.
isomers vs allotropes. I mean carbon has 3 allotrophes diamond graphite and buckmnsterfullene which are in different arrangements so what is the difference.Kindly hurry
Physically, graphite is opaque while diamond is transparent. Fullerene is yellowish green. Electrically, diamond does not conduct electricity due to absence of free mobile electrons. Graphite conducts electricity due to the presence of free mobile electrons. Fullerene does not conduct electricity.
@@catalyst44 but my question vs isomers vs allotrophes
I don't understand your question. Please make it clearer.
@@catalyst44 I want to understand the difference between allotropes and isotopes
They're totally different terms.
We can't hear you sir.
Oh really?
4x2=8 8=4n+2 4n+2=8 4n=8-2 4n=6 4n/4=6/4 n=3/2. It's not Aromatic compound because the number of n electron is not a whole number, it's in fraction and don't obey the Huckel's rule of Aromatic compound.the compound that have number of π electron that's equal to decimal or fraction is known as what?
Very well explained ✨
He's actually nice
thankyou
Thank you sir
n doesn't satisfy aromatic compound by giving 6/4
Thank you so much😊😊😊😊😊😊❤
4,6-diethyl-5-isopropylnonane
Great, we need more harder calculations on solubility
What a great lesson, i really understood it more than i've been taught in other website
From Ghana You’re the best😊
4th position it's when the I will be put
Please Mr catalyst may God blessed you as you opens our brain for education in chemistry❤😊😊😊❤❤❤
Omo broo I'm in Ss1 currently and about to write my midterm chemistry paper because of you im sure too pass. One love bro 🤍
Great explanation sir , great work sir
Very helpful
Great job. Please I need more videos
Thank you sir am doing BCM and I still need your help
Nice one sir!👍
