Definitions
n.noun · 名词
- 1.
Chemistry.
- ›any compound derived from phenol by the replacement of one or more of its ring hydrogen atoms by the nitro group.
- ›any of three water-soluble, crystalline isomers of such a derivative, having the formula C6H5NO3, occurring in yellow , pale-yellow , and yellowish solids, used chiefly as intermediates in organic synthesis and as indicators.
Examples
If an alkali is added, however, a highly dissociated salt of para-nitrophenol is formed, and the yellow colour is at once evident.
Thus para-nitrophenol has colourless molecules, but an intensely yellow negative ion.
This equilibrium curve, therefore, shows that o-nitrophenol and p-toluidine do not combine with one another.
