👉 The word you've mentioned is "methyl", which stands for methyl-ethanolamine and has a very interesting history. It's often used as a chemical compound to describe the structure of phenyl ketones, but there are more than just those two.
Here’s a humorous explanation: Imagine you're in a room full of cats, and one cat sneezes loudly. The other cats start laughing until they cry out loud! So, what if we had this funny word for every single molecule in our chemical world? It's called "phenyl". In chemistry, it's used to describe the structure of phenyl ketones. And let's take a look at an example sentence using it. Imagine you have a box full of chemicals and want to make sure all of them are safe to mix with each other. You've got a list of化学品，and you need to make sure they're compatible—no two molecules should react in the same way, right? So, how would you write that down? "All those boxes of chemistry contain chemicals like methyl-ethanolamine." Now you can mix up your substances without worrying about them getting mixed up. The word's history is fascinating, but let's not get all mushy and sentimental. What if we took a look at the chemical reaction between methyl-ethanolamine, phenyl ketones, and other chemicals? Well, that reaction turns out to be quite dangerous! You see, it involves a few different reactions,
