Vedclass · Answer

(A) $1$. The starting material is cyclopentane. Reaction with $Cl_2/hv$ (free radical chlorination) gives chlorocyclopentane $(A)$.$2$. Treatment of chlorocyclopentane $(A)$ with alcoholic $KOH$ (dehydrohalogenation) yields cyclopentene $(B)$.$3$. Ozonolysis of cyclopentene $(B)$ followed by reductive workup with $Zn/H_2O$ leads to the cleavage of the double bond,resulting in pentanedial,which is $CHO-(CH_2)_3-CHO$.

Identify $X$ in the following reaction sequence: Cyclopentane $\xrightarrow{Cl_2/hv} A$ $\xrightarrow{alc. KOH} B$ $\xrightarrow{O_3, Zn/H_2O} X$
