can someone give me a simple definition of an organic compound please? i haven't found one that tells me whether HCN is organic or not, which is the point of my question.
I'm pretty sure HCN isn't an organic compound.
In general, and organic compound is a compound that containts Carbon and Hydrogen. Organic compounds can have different structural isomers which affect their chemistry, whilst inorganic compounds do not (I'm not sure about this though....correct me if I'm wrong!). Also organic compounds tend to be more complex and larger than inorganic compounds...well they do from my experience....
Yes, I think HCN, CO2, CO, HCO3-, and CO3 2- are exceptions, because they are small and organics tend to be large molecules. However CH3CN would be organic.
I think an organic compunds is a molecule thats main basic structure is a carbon-hydrogen chain or loop.
