In this video, we're going to distinguish between intramolecular and intermolecular bonds. Chemical bonds between atoms can either be intramolecular or intermolecular bonds. Number 1 here is focused on the intramolecular bonds, which are interactions between atoms within the same molecule. The number 1 mentioned in the text corresponds with the number 1 on the left-hand side of the image for intramolecular bonds. Let's take a look at the image on the left-hand side. Notice that in the middle, we're showing you a water molecule, we are showing you H2O, 2 Hydrogens, 1 Oxygen atom. These lines forming between these different atoms represent a type of chemical bond that we'll discuss more as we move forward. But notice that these bonds, these chemical bonds, are forming within the same water molecule right here, and these two bonds are almost trapped within the same molecule. You can think the 'intra' can remind you of the word 'trapped', and so they're going to be trapped within the same molecule just like this example here is trapped behind bars.
Intermolecular bonds, on the other hand, are interactions between atoms of different molecules. The number 2 that we have up above in the text is going to correspond with the number 2 that we have down below in our image. Let's take a look at the right-hand side of our image this time. Here, we show two water molecules. We're showing you one over here and another water molecule over here. This time we're focused specifically on a bond that is forming between these two different molecules. Since it's forming between two different molecules, it's not going to be trapped within the same molecule, and so intermolecular bonds are not trapped. You can think that the 'ter' here cannot be used to spell 'trapped', and so it's not trapped and instead is forming between different molecules. It's almost like how you can see one person giving a high five to another person. So it's almost like one molecule is giving a high five to another molecule right here, and this high five would be this right here, forming between different molecules. You can think that 'inter' is for between different molecules.
Hopefully, this will help you better distinguish the difference between intramolecular, which are trapped within the same molecule, and intermolecular bonds, which are not trapped within the molecule and form between different molecules. We'll be able to get some practice with these ideas moving forward in our course, and I'll see you in our next video.
