Answer 2

It seems like you've provided a chemical equation fragment. The equation appears to represent the addition of a water molecule (H2O) in a chemical reaction, which is commonly known as hydration.

In this case, it looks like you're suggesting the hydration of a compound or functional group represented by "Ch2" with an -OH group (hydroxyl group).

If you have a specific compound or context in mind, I can try to provide more detailed information or help with any questions you have regarding this reaction.
