Toluene $\xrightarrow{{KMn{O_4}}}A\xrightarrow{{SOC{l_2}}}$ $B\xrightarrow[{BaS{O_4}}]{{{H_2}/Pd}}C$
the product $C$ is :
Major final product $(Z)$ is
${K_2}Cr_2{O_7}/{H^ + } + y \to \mathop {C{r^{ + 3}} + Others}\limits_{(green)\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} $

image $\xrightarrow{{A{c_2}O}}A\mathop {\xrightarrow{{B{r_2}}}}\limits_{C{H_3}COOH} B\mathop {\xrightarrow{{{H_2}O}}}\limits_{{H^ + }} C$ would be
