# Ch

## Recommended Posts

Is that an official name for CH?

I know that NH3 is named Ammonia. I also know that NH3 is stable wheras CH isnt.

CH is no existing chemical, but sometimes all the hydrocarbons are called "$C_x{H_y}$".

As you learned before in this thread, you can determine how many hydrogen you will need to make the carbon get its desired 8 electrons (like the nitrogen in ammonia).

Thank you

I think your problem stems from your interpretation of the diagram in the other thread (apologies for cross-threading). You saw the diagram as a group of molecules joined to each other (you mentioned ammonia and CH and CH2). The trouble is that the diagram represents one single molecule, not a series of separate molecules joined together. So that's why it contains things like CH and CH2 which aren't stable on their own. As part of a larger molecule they can be very stable indeed.

okies that helps, thank you!
