So imagine you have two toy blocks - one is red and one is blue. You can stick them together to make a new toy block that is both red and blue, right?
Now imagine instead of toy blocks, we have molecules. Some molecules have a part that is like the red block, and a part that is like the blue block. But instead of sticking them together with our hands, they can stick together on their own.
When the red and blue parts of two molecules come together and stick, they make a new molecule called an imine. This imine can have some interesting properties - like being able to make certain chemical reactions happen more easily.
Scientists use imines in all sorts of things, like making medicines or new materials for technology. But even if you're not a scientist, it's fun to know that molecules can be like toy blocks coming together to make new things!
