Total sum of oxygen atoms and $\pi$-electrons is $3+8=11$
Total number of oxygen atoms $=3$
Total number of $\pi$-bonds $=4$
$\therefore$ Total number of $\pi$-electrons $=8$
$\mathrm{X} \xrightarrow[Zn/H_2O]{O_3}\mathrm{A} \xrightarrow{[Ag(NH_3)_2]^+}$$\mathrm{B}(3-\text {oxo}-\text {hexane dicarboxylic acid})$
$X$ શું હશે ?
