Vedclass · Answer

(A) The reaction shown is a coupling reaction between $N,N$-dimethylaniline and diazotized sulfanilic acid in the presence of a base $(OH^-)$. This reaction produces $4$-dimethylaminoazobenzene-$4'$-sulfonic acid sodium salt,which is commonly known as $Methyl \ orange$. $Methyl \ orange$ is a well-known acid-base indicator used in titrations,which changes color depending on the $pH$ of the solution (red in acidic medium and yellow in basic medium).

Consider the following reaction. The product $X$ is used:
