Give the diazotisation reaction of aniline. Also give the chemical reaction involved in the preparation of red azo dye and light yellow azo dye.
Diazo-coupling is use ful to prepare some
Coupling of benzene diazonium chloride with 1-napthol in alkaline medium will give:
Benzene diazonium chloride on reaction with aniline in the presence of dilute hydrochloric acid gives:
Which of the following reagents would not be a good choice for reducing an aryl nitro compound to an amine?
A compound $$X$$ has molecular formula $${C}_{7}{H}_{7}NO$$. On treatment with $${Br}_{2}$$ and $$KOH$$, $$X$$ gives an amine $$Y$$. The later gives carbylamine test. $$Y$$ upon diazotisation and coupling with phenol gives an azo dye. Thus, $$X$$ is :
Which statements are correct?
