Hydrogen Bonding and Common Mistakes

To see all my Chemistry videos, check out
socratic.org/ch...
Hydrogen bonding can be so confusing, and in this video we talk about some common mistakes. Hydrogen bonds are intermolecular forces between molecules. They form because one atom has a high electronegativity, so it gets a partial negative charge, and the hydrogen gets a partial positive charge.

[@tdewitt451]

Analogies are always imprecise. But through my years in the classroom, I've never encountered any student confusion about this issue. Because, honestly, when students are learning this for the very first time, they just need an "image" (like magnets) to make the concept more relatable. It's only people like you and me (who understand the nuances between magnetic and electrostatic forces) who worry there'd be confusion. Most 14 year-olds just think "OK, they stick together like magnets."

[@ifrahariff2018]

Thank you so much for your video! It was really useful and I love the effort you've put into it. But, one question: isn't the ethanol molecule meant to have a V-shape? I know this video is meant for beginners but I needed clarification. Would its shape not affect its ability to bond?

[@tdewitt451]

+Ifrah Ariff Good question! There are many ways to draw the ethanol molecule, and no way is 100% correct, because we're trying to represent a 3D object in two dimensions. However, the shape of the molecule isn't going to affect its Hydrogen-bonding ability.

[@ifrahariff2018]

But doesn't the length of the alkyl chain affect the alcohol's intermolecular bond strength, and thus its boiling point?

[@tdewitt451]

+Ifrah Ariff The strength of a single Hydrogen bond will always be (about) the same. If the alkyl chain is longer, the molecule is heavier and there's more to hold in place. So you might say the *total* intermolecular strength is lower, but strength of an individual hydrogen bond isn't affected by molecular size or shape.

The name is less misleading in German, where it basically is called "Wassterstoffbrückenbindung" which is German science-babble for hydrogen-bridge-bond, thus implying that the bonding is just a weaker connection between two molecules, not a strong bond between Hydrogen.

[@thebraveminion]

Ok.. so you said that C and H share those electrons evenly... Okay... But why tho? I mean... Why is oxygen hogging the electrons whereas carbon is like: "Yeah, I'm good, we can share equally"?

[@tasneemshariif8788]

RavenclawFTW lol I know right .. Sometimes that confuses me too but I guess carbon is less electronegative than Oxygen ... The more electronegative element essentially " hogs" the electrons ...am I right b

[@cheeesonator]

Look up the octet rule. Or Just look up electronegativity.

[@iBenTV]

oxygen is more electronegative than hydrogen, so when O-H share electrons oxygen pulls- or "hogs"- the electron away from hydrogen. There isn't a big difference in electronegativity in a C-H bond so they share the electron equally :)

[@fawzibriedj4441]

Carbon and Hydrogen do not share electrons equaly, the polarity is just not strong enough The vidéo is full of wrong stuff

[@gibsonomwa1690]

thus the more electronegative element has a slight negative charge and the less electronegative element a slight positive charge

[@Dj992Music]

I'm confused on exactly how to determine whether there is a hydrogen bond. Does hydrogen bonding ALWAYS exist if a N, O or F of one molecule comes in contact with a H from another molecule? For example, is there hydrogen bonding between propanone and chloroform? Does there have to be a covalent bond between H and N, O or F where hydrogen bonding exists? Would very much appreciate an explanation

[@MrUgobright]

Everything he said is wrong is actually not true. First, Hydrogen bonds can be intramolecular (within the same molecules) here are examples: Succinic acid, glycol, 2-hydroxybenzoic acid!!! Also, google "dihydrogen bond" you'll realize there can be H---H hydrogen bond. Also CH group can form C-H---O hydrogen bond.

[@tdewitt451]

Everything I said is wrong?!? Really? It's all lies? Of course not. You bring up some good points, but they're all extremely advanced points, with examples that often happen only very rarely. This video is a basic introduction to the topic. Most students don't understand the topic at all, so I'm trying to explain it in an easy way that makes sense at first. When most viewers struggle to understand just the basics of Hydrogen bonding, it would be a mistake to add in all the confusing exceptions that you mention here. Those are more advanced topics for later.

[@kellyc5108]

+Tyler DeWitt you could have mentioned that intramolecular H bonds can be formed in some rarer/more advanced cases instead of saying that H bonds MUST be intermolecular and any bonds formed intramolecularly MUST NOT be H bonds..because thats not true and can be misleading...

[@tdewitt451]

+Kelly C I could have, but I didn't. Because I'm trying to keep things simple and this topic is confusing enough as it is. If you're interested in teaching (and I hope you are!), the *most* important question a teacher can ask is, "What can I leave out to make this clearer?" Once a student understands the main point, you can always get more advanced. But if you throw in a bunch of advanced stuff and it gets confusing, that student will never have a chance to learn the more advanced stuff, because they're totally confused and turned off. If you're interested in my philosophy on this, you should check out my TED Talk on this subject.

[@tdewitt451]

+Kelly C The great architect Mies van der Rohe said, "Sometimes you have to lie in order to tell the truth." That's how I feel about science education. I have a PhD in this stuff, so I'm guessing that many things you think are true and certain, I've learned they're more complicated. If we want to communicate science clearly, we've got to decide--at each grade level--what is appropriate to leave out.

[@kellyc5108]

+Tyler DeWitt its actually the first time that i came across your videos. and by looking at the title and the description box, i didnt know the audience you are aiming at is the beginners so i was expecting some more advanced level of knowledge. anyways, thank you for sharing a bit of your teaching philosophy! i will definitely check out your TED talk. it should help me with my final year project haha.
