FAQ
Frequently Asked Questions
No, it is a highly specialized scientific term used almost exclusively in chemistry.
'Nitroso' refers to the NO group (-N=O), while 'nitro' refers to the NO2 group (-NO2). They are different functional groups.
No, in standard usage, it functions as an adjective (e.g., nitroso compound) or a combining form.
Some can be, as they are often reactive and some are known to be carcinogenic, but this depends entirely on the specific compound. The term itself only describes a chemical structure.
