Homework Statement
The problem was to tell how many hydrogen bonds there are between cytosine and guanine. and I know there are three. http://study.com/cimages/multimages/16/Cytosine_Guanine_base_pair.png
But I think I might be misunderstanding the hydrogen bond concept.
I thought that hydrogen bonds only formed between O, F and N when they are also bond to H atom. And therefor CO2 fx does not form hydrogen bond with water as the oxygen atoms in the CO2 are not bonded to H atom.
In the cytosine-Guanine there is a hydrogen bond between Oxygen atom and NH2 but the Oxygen atom is only bond to Carbon, so why is there a hydrogen bond?
And N makes hydrogen bond with NH but the N is only bond to two C atoms
please explain.
