Nitrobenzene is an oily yellow liquid with an almond-like odor. It may be pale yellow-brown in appearance. It dissolves only slightly in water, but very easily in some other chemicals. Nitrobenzene is produced in large quantities for industrial use.

How can you identify nitrobenzene?

The detection of nitrobenzene is based on its partial reduction with zinc in slightly acidic medium to yield phenylhydroxylamine, acid-catalyzed rearrangement to form a mixture of 2- and 4-aminophenol, and formation of indophenol blue by 4-aminophenol on oxidative coupling with an alkaline phenol solution.

Spraying once in every 25 days after 15 days of sowing/transplantation increases the yield significantly. No such relation with urea application as it induces flowering and thus flavors good yield. Nitrobenzene is a plant energiser and flower stimulant.

Why is nitrobenzene yellow?

Effects on chromophore

For example, benzene does not display color as it does not have a chromophore; but nitrobenzene is pale yellow color because of the presence of a nitro group (−NO₂) which acts as a chromophore. ... An auxochrome helps a dye to bind to the object that is to be colored.
