  4. An alcohol A, when heated with conc. H 2 SO 4 gives an alkene B. When B is bubbled through bromine water and the product obtained is dehydrohalogenated with excess of sodamide, a new compound C is obtained. The compound C gives D when treated with warm dilute H 2 SO 4 in presence of HgSO 4. D can also be obtained either by oxidising A with KMnO 4 or from acetic acid through its calcium salt. Identify A, B, C and D.

Q. An alcohol $A$, when heated with conc. $H _{2} SO _{4}$ gives an alkene $B$. When $B$ is bubbled through bromine water and the product obtained is dehydrohalogenated with excess of sodamide, a new compound $C$ is obtained. The compound $C$ gives $D$ when treated with warm dilute $H _{2} SO _{4}$ in presence of $HgSO _{4}$. $D$ can also be obtained either by oxidising $A$ with $KMnO _{4}$ or from acetic acid through its calcium salt. Identify $A, B, C$ and $D$.
