i got 99 in my 12th class chemistry, 1 mark deducted coz i wrote cast iron instead of wrought iron totally missed it . I m mhere to refresh my memory. love this subject.
How was it in class 11. How many hours did you study? Which books did you do? I feel lost in eleventh. Don't know what to do, how to do... Please help me
I was always grasped that water exapands when it freezes but I never really understood the mechanics behind it. Showing how it makes almost a honeycomb pattern when the molecules freeze in place (I know they still vibrate but mostly stay put) really make it clear why ice is less dense than water. It probably seems like common sense, but typically things actually become more dense in a solid form so it's neat.
Love the poll questions leading me to these videos as little reminders about topics and this is perfect because im enhancing both chemistry and and biology knowledge
Hey! Firstly I wanted to thank you for your videos. I have a lot of interest in Chemistry yet I find reading a textbook to be less than effective for me. This very much helps me understand concepts! Aside from this, I wanted to ask a more fundamental question on why water (H2O) is polar? I understand because of the displacement of charge, yet why is it bent in such a way? I vaguely remember learning about London Dispersion Forces yet I can't remember why that occurs. By any means, informative video- and thank you again!
Agreed on textbooks, they do tend to be rather static. I'd say my own understanding of chemistry is enhanced more creating videos rather then writing text. When we think about the shape of water, that is largely a result of how the electron clouds around atoms (and from the lone pairs) interact. They are negative clouds and they push away leading to the shape of the molecule. This video should help you visualize the phenomenon (VSEPR: ruclips.net/video/Moj85zwdULg/видео.html). This is the web app I use in the video: phet.colorado.edu/sims/html/molecule-shapes/latest/molecule-shapes_en.html . Polarity had to do with how the bonding electrons are shared between atoms. When the sharing is unequal, like with water where the bonding electrons are attracted more to the Oxygen atom, we have an unequal distribution of charge and therefore polarity. I created this video to help my students understand polarity ruclips.net/video/OHFGXfWB_r4/видео.html . Great to hear you are interested in chemistry! --- Dr. B
First, I really like to appreciate your idea of making simulation and given them proper or approximate value to the molecule, electrons and protons. It's helps me to visual our surroundings and how it works and Thanks brother for the information now i got some ideas about how bonding works in hydrogen atom.
Thanks a lot I couldn't understand the concept of HB in both water and ice but this video helped me a lot. Thanks for explaining it in simulation. I couldn't understand it from my textbook but you man surely did cleared a lot of my confusions.
At a certain temperature there isn't much hydrogen bonding. The higher the temperature the weaker the hydrogen bonding. This is sort of interesting: pubs.acs.org/doi/10.1021/jp951561t

Hey sir just want to ask u one thing,which software did u use for these animations>I too wanna try out just to learn as we learn by doing.Is it python code?Or something else?
Interesting. The image on this page is awesome: en.wikipedia.org/wiki/Clathrate_hydrate I've not used Material Studio. Most of the molecules I use in my simulations and images are already rendered. So I'm not sure I'll be much help. It's a valuable skill to have, though, - Dr. B
So helpful! Especially to see how frozen water forms crystals. Thank you!
Glad it was helpful! I'm sort of proud of this particular video.

Better explained than my prof. greetings from Germany!

Thanks. It was very clear being able to see the action of the molecules visually

Awesome, glad I could help!
Thank you for this fantastic video. I'm currently doing biology 12, and it really helps me understand how molecules and hydrogen bond work.😊
Excellent presentation here
Best video for hydrogen bonding. Thanks a lot Sir!
Thanks a lot I couldn't understand the concept of HB in both water and ice but this video helped me a lot. Thanks for explaining it in simulation. I couldn't understand it from my textbook but you man surely did cleared a lot of my confusions.
You are most welcome! It's a tricky concept without a visualization.
@@wbreslyn yeah it is. I couldn't understand anything that my teacher explained in online classes.
Online classes are tough to teach and tough to learn from most often.
Itssss awesome❤ lovedd ittt😇
Great information 👍❤️
Thank you sir.This really helped me a lot
Thank you for this fantastic video
Very helpful! Thanks!
very helpful, knowing my teacher harmae
Excellent!
Sir video is very nice and very helpful
Thanks, glad I could help! --- Dr. B
I love your videos! They make me enjoy learning Chemistry. Thank you!
You're very welcome!
Live long sir! Thank you
thanks for the simulation sir... but why does hydrogen bond break during high temperature? does temperature effect the charge to get weaker?
At a certain temperature there isn't much hydrogen bonding. The higher the temperature the weaker the hydrogen bonding. This is sort of interesting: pubs.acs.org/doi/10.1021/jp951561t
@@wbreslyn thanks a lot sir
What is that middle part??
Nice video bro🤓
Brilliant!
Would it be possible to simulate the behavior of water and hydrogen bonds between 280K - 270K? I'm wondering how it would look like.
What is the boiling point and freezing point of water if we remove hydrogen bonding in water
If you remove them, there will be no bonding between water molecules and water will be only gas. I only suggest that.
Waters Boling point 100°c
0°c freezing point
Sir please make a video on Lewis dot structure. Sir, I have many doubts on this topic. And I am sure you will clear my all doubts.
This should clear your doubts!

What application used ?

Thanks doc

Hello , How can i draw clathrate hydrate structure 2 using Material Studio or any software ,thank you very much for your help
Interesting. The image on this page is awesome:
en.wikipedia.org/wiki/Clathrate_hydrate
I've not used Material Studio. Most of the molecules I use in my simulations and images are already rendered. So I'm not sure I'll be much help. It's a valuable skill to have, though,
- Dr. B
thanks for explanation
Glad it helped!
Which program did you use?
A program called AtomSmith. --- Dr. B
Thankyou sir
Anytime!
Can you explain why oxygen can only undergo two hydrogen bond?
so cool
amazing
Thank you! Cheers!
Pls video on carbon family
Do you mean bonding, like Lewis Structures? --- Dr. B
great video ^^
Thank you! --- Dr. B
sir what will happen if hydrogen bonding in water does not exist at all?
Our world would be very, very different place!

great
Thanks!
