Hydrogen bonding

[baby00040007]

Answered my questions girl frennn!

[stojanovicvlada2009]

Everything is ok , but you are talking about intra not intermolecular forces...

[thomasreed92]

Thank you so much!!! I am a first year medical student in London and my teacher at school never taught this to me properly and now I finally get it. The last minute and a half was soo helpful. Ahh so happy!! :D

[jayrulz13]

i dunno if you are still making videos but could you please do one on dipole moment ???

[anisotropicentity]

i just read covalent bonds are the strongest type of bonds y is it so??

[Alex123McCarthy]

I thought you were a 12ish year old boy until i saw the feminine wedding ring

[sneedledout]

good thing I already knew most of this, otherwise I would be way confused by the way you explained it

[yzy010858]

so in one mole of water or ice, how many mole of hydrogen bonding will be formed?

is it two mole?

[no1man5]

you da man!!!

[Coveristism]

OMG! So very useful, than you so very much. You should upload a vid for Van der waals forces.. i will be very pleased . :)

[baby00040007]

@Coveristism Very pleased, lol

[BlindLightbulb]

words cannot express my gratitude. So I'll just use symbols. <3 :D ^_^

[XHUMBITO1]

thanx dude :D.

[yijern]

thank you so much! It helped me not only in my chem but also a little in bio~ :D

[guesswhothisis]

Thank you so much for making this video. I really liked your cut out drawings compared to just paper. It helped me understand it a lot better.

[DrKojiin]

This vid is awesome

[rezaeijavan]

Thank you , Very Helpful 

[frannn666]

thanks a lot this helped me understand the concept a lot more

[dwncbl17]

thank you so much. this helped me a lot.

[AmirTunes]

You are an amazing teacher!

[007ashlea]

I had to make a youtube account just to tell you how much you helped! I wish my chem teacher would have taught me the way you teach! Thanks sooooo much!

[lovedog49507]

So, would H and F- be a good example of hydrogen bonding ?

[roller237]

OK so what makes the hydrogen a partial positive and the oxygen a partial negative? Thats the only part I dont get. =(

[highflyer0509]

you are so amazing. you saved my girlfriend!

[asasolsh1]

thank you:D

[HPAbby]

THANK YOU SO MUCH! I LOVE the way you explained this, I tried to read this in my chem. book but I couldnt picture it, now I totally get it! THANK YOU SO MUCH!!!

[BizNez32]

damn ima bust a nut lol

[Mongoosemcqueen]

Damn you have a sexy voice, you made this all sound so sexy, I love it when you say hydrogen it just rolls off your tongue like honey oh god I want to bond with you baby

[rbaleksandar]

Very interesting. Well done. :P

[moogoesthecow7]

o damn!

[EineAlpensinfonie]

Thank you Dear Lady.

You made my Life easy to be able to teach hydrogen bonding!!

[ElliotFer]

i think you should mention that the hydrogen bonding is between the hydrogen atom and the neighboring atom's lone pair electrons instead of saying it's being bonded with the neighboring atoms

otherwise, great video

[imin5thgrade]

thankksss a lot

helped me lot

yee

[ProNerdGamer]

My chemistry teacher overestimates the learning ability of my class because we're in CHEMISTRY, or something like that...

On a positive note, a good interactive lesson: very through.

[sunnihunni93]

omg im gonna fail!

[sandi0688]

thank you so much. it is a great video!! it helped me a lot!!

[123myworld]

awesome..i hav my chemistry paper tomorrow...:)

[toxie1736]

Thank you!

[jenvb01]

thank you. i was about to fail my biochem test.

[Hellsconsort]

This is a very nice video - with detail, but explained in a very understandable way.

I never thought of using cut outs for learning or figuring out types of bonds also. Thank you for this idea! Much easier than writing out on lots of pieces of paper.

[PHATJaime]

Thank you so much. EXCELLENT and simple explanation!

[dazzlepecs]

the graphics were amazing!! Thanks for uploading and explaining!

[ledzepln243]

Best explanation of hydrogen bonds i've heard! thanks alot for the post

[djGZMN]

This video made everything clear. Appreciate it!!

[raimonk]

thank you!

[AlpherDog07]

thanks helped me with my a level

[kaykentucky]

HEY!! GOOD STUFF!! love ur explanation :D

[Alyonius]

Excellent video, very well explained. Thank You!

[julianajuliana]

greattt! thank's

[xkon89]

GREAT explanation O.O

[XdershizX]

you are by far the smartest person on youtube!

[krystalsjohnson]

Thank you for posting this video!

[smashurface4]

Wow thank you so much for making this video. It is awesome

[slimmaite]

OMG! your explanation really helped tremendously...thanks

[BRIGHTONB]

wow you do not know how much that helped!!!!

THANKS SO MUCH <3

[wyzz777]

Oh wow thank you SO SO much! I've got my Chemistry exam tomorrow and this has helped me SO much :)

[duyu]

Thanks so much!

I was doing homework and was confused as to why molecules such as CH3F and CH20 do not form hydrogen bonds, but your explanation of hydrogen bonding between guanine and cytosine elucidated the rules governing H bonding.

A frustration has been put to rest. :)

[sophienna]

a great explanation, thank you so much. You reminds me me Chemistry teacher, both of you are great! :)

[calexculux]

u talk like a young man,that's why I loved the video because it shows u are good.

[Sectorsophia]

Great video! I wish you were my chemistry teacher!

[masteryan]

Thanks you so much!!

[TTUchem1010]

Cool, so I guess it answered your questions?

[masteryan]

Yeah it was good! Your channel is great.

[mdr1988]

Its pretty good.

Just a couple of things; first thing I always state out when disgusting this subject; H-Bonding isn't bonding! It's interaction!

Secondly you might have wanted to go a little bit deeper into elektronegativity. Once one understands the basics of that, the rest become clearly logic. And the DNA-part at the end was a bit too much. You could have seperated that to form a new video (or part II).

I really did like it though. Do you make quantum chemistry vids as well? Greets

[TTUchem1010]

Thanks for the good input.

I did get carried away, and it could use some editing. I still hope it's helped someone somewhere! :)

Someday, I'll make some quantum videos.

[sonydevout]

@TTUchem1010 I'm actually very thankful for the DNA part. I knew it was an example of hydrogen bonding, but I wasn't positive on why. Considering I have to present tomorrow, it helped A LOT. It was a great video. You might be better at explaining then my H. Bio teacher(:

[metalmaniac767]

@mdr1988 2:53 .

[123456vwxyz]

@mdr1988

Hydrogen Bonding is a definately a kind of bonding inetraction, It is not just an interaction.

[rocker9455]

@mdr1988 I'd have to disagree with your view on that section of the video. I found it absolutely fascinating!

[veraraj]

there are other intermolecular forces like van der Waals or dispersion forces... when do these forces happen?

[TTUchem1010]

All molecular substances have dispersion forces (also called London or weak van der Waals). They're attractions of temporary dipoles, and they happen when the electrons in a covalent bond aren't shared equally at a specific instant. This creates the "football stadium wave effect," inducing temporary attractions in the nearby molecules. These induced dipoles make the molecules stick together.

Dispersion forces increase with increasing molecular weight and increasing surface area.

[veraraj]

thank you =)

[mielectric1]

well put, how about covalent bonds

[TTUchem1010]

Covalent bonds involve a sharing of electrons. This happens when each atom has a similar "desire" for electrons (electronegativity). The end result is atoms that "feel" more like the noble gases. Rule of thumb: nonmetal atoms form covalent bonds with other nonmetal atoms.

There are two general types of covalent bonds: nonpolar covalent (equal sharing) and polar covalent (unequal sharing).

Covalent bonds are represented by a line in a chemical structure. (1 line = 2 electrons)
