The reaction of amines with NaNO(2)+HCl ...

The reaction of amines with `NaNO_(2)+HCl` depends on the type of the amine and whether it is aliphatic or aromatic. The diazo group developed in aliphatic primary amines is rather highly unstable and decompose to produce mainly alcohols. Secondary amines react to give yellow oily liquids.
Which of the following amines give yellow oily liquid nitroso compounds on reaction with `NaNO_(2)+HCI`.

A

`CH_(3)CH_(2)NHCH_(3)`

B

C

D

Both a & b

when an primay aromatic amine is treated with NaNO_(2)+HCl at 0^(0)-5^(0)C , a diazonium salt is formed and the reaction is called diazo reaction. In this reaction mineral acid must be added to prevent the coupling reaction of diazonium salt with excess of aryl amine. Diazonium salt is highly useful in the synthesis of number of coloured dyes. For the following diazonium ion the decreasing order of reactivity of these ion in azo-coupling rcaction

    A reaction of aryl diazonium salts that does not involved loss of nitrogen takes place when they react with phenol and aromatic amines. Aryl diazonium ion relatively is weak electrophile but has sufficient reactivity to attack strongly activated aromatic ring. The reaction is known as azo coupling. The coupling of diazonium ions with phenols or other electron rich aromatic compounds is useful commercial reaction as azo compounds are highly coloured and many of them are used as dyes. Which of the folllowing is responsible for the colour of diazo compounds ?
