Under what reaction condition (acidic, basic) the coupling reaction of aryl diazonium chloride with aniline is carried out?
In strongly basic conditions, benzenediazonium chloride is converted into diazohydroxide and diazoate as both of which are not electrophilic and do not couple with aniline.
$$\mathrm{{C_6}{H_5}\mathop N\limits^ + \equiv NC\mathop l\limits^ - + \mathop {OH\,S{O_2}C{H_5} - N = N - OH}\limits_{Diazohydroxide}}$$
Similarly, in highly acidic conditions, aniline gets converted into anilinium ion. From this, result aniline is no longer nucleophilic acid and hence will not couple with diazonium chloride. Hence, the reaction is carried out under mild conditions, i.e., $\mathrm{pH}-4-5$
$\underset{\text { Aniline }}{\mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2}+\mathrm{H}^{+} \rightarrow \underset{\substack{\text { Anilinium ion } \\ \text { (coupling do not occur) }}}{\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{N}} \mathrm{H}_3}$
Predict the product of reaction of aniline with bromine in non-polar solvent such as $\mathrm{CS}_2$.
Aniline on reaction with $\mathrm{Br}_2$ in non-polar solvent $\mathrm{CS}_2$ produces 2, 4,6 tribromo aniline.
Aniline has high reactivity towards bromine as it gives the triply substituted product.
Arrange the following compounds in increasing order of dipole moment.
$$\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_3, \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{NH}_2, \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH}$$
Dipole moment of amine, alcohol and hydrocarbon can be explained on the basis of bond polarity of $\mathrm{C}-\mathrm{H}, \mathrm{N}-\mathrm{H}$ and $\mathrm{O}-\mathrm{H}$ bond. As the bond polarity increase, dipole moment increases $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_3<\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{NH}_2<\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH}$
