Nitrogen Containing CompoundHard
Question
Which of the following statement is true ?
Options
A.Trim ethyl amine forms a soluble compound with Hinsberg reagent and KOH.
B.Dimethyl amine reacts with KOH and phenol to from an azo dye.
C.Methyl amine reacts with nitrous acid and liberates N2 from aq. solution.
D.None of these.
Solution
Among the given statement only (c) is true. As methyl amine liberates N2 on reaction with nitrous acid. CH3 - NH2 + 2HONO → CH3 - ONO + N2 + 2H2O
While dimethyl amine and trimethyl amine form insolibe compound with Hinsberg reagent and KOH.
R2NH + C6H5SO2Cl
C6H5SO2NR2
R3N + C6H5SO2Cl R3N
insoluble
Azo dayes are not formed by seconadry amines.
