Question

$1)$ How will you carry out the following conversions?

$A)$ $\text{toluene}\to p-\text{toluidine}$

$2)$ How will you carry out the following conversions?

$B)$ $p-\text{toluidine diazonium chloride}\to p-\text{toluic acid}$

Answer 1

$A)$ The conversions of toluene to $p-$toluidine can be carried out in two step processes.

Nitration of toluene



Reduction of nitro group in $p-\text{nitrotoluene.}$


$B)$ This reaction can be achieved by nucleophilic substitution of diazonium group by cyanide group and on further hydrolysis gives toluic acid.
