Definition of nitro group in English: nitro groupnoun Chemistry A group —NO₂, attached to an organic group in a molecule. Example sentencesExamples - The most widely used method of preparing aromatic amines, for example, involves a nitration of the aromatic ring and subsequent conversion of the nitro group to an amino group.
- Dyes are prepared by a nitration addition reaction to aniline, followed by reduction of the nitro group using sodium sulfide.
- The twisted geometry of the nitro group with respect to the aromatic plane plays a key role in triggering such a photoprocess.
- Yet, replacement of a sulfonic acid group in a non-mutagen with the nitro group in structure 4 converts it to a mutagen, which was predicted correctly by all the models.
- Accumulation of nitrotyrosine, a stable product of the addition of a nitro group to the benzene ring of tyrosine by peroxynitrite is thus a stable marker of pathology within cells and tissue lesions.
