What is Compounds: Definition and 236 Discussions

Carbon compounds are defined as chemical substances containing carbon. More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds. Carbon is tetravalent but carbon free radicals and carbenes occur as short-lived intermediates. Ions of carbon are carbocations and carbanions are also short-lived. An important carbon property is catenation as the ability to form long carbon chains and rings.

    The oxidation number of nitrogen in the following compounds.

    I worked on this problem for quite a while last night and I'm not at all sure if my answers are correct. This is the problem I’ve been given: I know nitrogen exists in the 3-, 3+ and 5+ oxidation states. I would think that they would give me at least one of each. I'm REALLY not sure about b...

    Emission Spectra for Elements and Compounds

    Simply put, does it ever change? That is, does the line spectrum of a particular element or compound ever change? I've been searching all over, but I'm getting different answers! :grumpy:

    Chemistry Ques. re: structure of organic compounds

    Okay, using the structure of organic compounds. Are supposed "natural" vitamin C extracts from rose hips better than synthetic tablets of vitamin C? I have to answer this and if another source is used document it. So If you have the answer can you tell me where you found it? Thanks in advance...

    Atom Simulator: Kids Create Compounds & Play

    Question on Ionic bonds and compounds
