An organic compound $\mathrm{A}$ has the molecular formula ${\mathrm{C}}_4{\mathrm{H}}_8{\mathrm{O}}_2$ on hydrolysis given product $\mathrm{B}$ and $\mathrm{C}$ having molecular formula ${\mathrm{C}}_2{\mathrm{H}}_4{\mathrm{O}}_2$ and ${\mathrm{C}}_2{\mathrm{H}}_6\mathrm{O},$ respectively. $\mathrm{B}$ is used as vinegar in cooking. Identify $\mathrm{A},\mathrm{B}$ and $\mathrm{C}$; and also write the chemical equation involved in the formation of $\mathrm{B}$ and $\mathrm{C}$.
