Nitro compounds are named as the nitro derivatives of the parent alkane in both the systems of nomenclature. This is done by adding the prefix nitro to the word root of the parent alkane.
Alkyl nitrites are named by adding the suffix nitrite to the alkyl group. For exampleCH3-O-N=O is Methyl nitrite.
C2H5-O-N=O is Ethyl nitrite.
