Question

Identify the reagents A, B, C, D, E and F required for the following conversion.
$C_6{H}_{5}N{O}_2\stackrel{A}{\to }{C}_6{H}_{5}N{H}_2\stackrel{B}{\to }{C}_6{H}_5{N}_2^{+}C{l}^{-}\stackrel{C}{\to }{C}_6{H}_{5}Cl\stackrel{D}{\to }{C}_6{H}_{5}OH\stackrel{H_{2}S{O}_4}{\to }E+F$.

Answer 1

Reagents are as follows :

$A\to Sn+conc.HCl.$
$B\to NaN{O}_2+Conc.HCl$.
$C\to C{u}_{2}C{l}_2+HCl$.
$D\to NaOH$
$E\to 2-$hydroxy benzene sulphonic acid.
$F\to 4-$ hydroxy benzene sulphonic acid.
