 Okay, I just want to show you guys kind of a spectrum of bonding relative to, like, bonding polarity relative to their difference in electronegatives, okay? So if we have the spectrum, okay, we're going to write a bonding spectrum. And over here is, on one hand, nonpolar covalent. So no electronegative difference. And here we have ionic, the really ionic. So what we'll find is that there's this spectrum of different types of bonds. So at 0.0, and this is all in device, the units of electronegativity. So 0.0 to about 0.4 device. All of these are your nonpolar covalent bonds. So 0.4 is kind of a nice benchmark because that's your CH bond, okay? And those are kind of oils, and oils we say are nonpolar. So anywhere from here to here, I want you to say nonpolar. So from 0.4 to 2.1, we have polar covalent. These give rise to more strong Vanderbos forces, okay? So intermolecular attraction. Or if you want to think of it, they have a bigger difference between the electronegativities of the two atoms that are the two bonding atoms. And then once you get to 2.1, then you're at ion. So anything above 2.1 are all those salts and stuff like that, like sodium chloride or, you know, potassium bromide. Okay, so very big difference in electronegativity. Is everybody okay with this? So this is what we're talking about is difference to tell whether that bond is polar
