MCQ
An alkene $A$ on reaction with $\mathrm{O}_{3}$ and $\mathrm{Zn}-\mathrm{H}_{2} \mathrm{O}$ gives propanone and ethanal in equimolar ratio. Addition of $HCl$ to alkene $A$ gives $B$ as the major product. The structure of product $B$ is:
- A$Cl - C{H_2} - C{H_2} - \begin{array}{*{20}{c}}
{C{H_3}} \\
{|\,\,\,\,\,} \\
{CH} \\
{|\,\,\,\,\,} \\
{C{H_3}}
\end{array}$ - B$\begin{array}{*{20}{c}}
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{H_2}Cl} \\
{\,\,\,\,\,\,\,\,\,\,\,|} \\
{C{H_3} - C{H_2} - CH - C{H_3}}
\end{array}$ - ✓$C{H_3} - C{H_2} - \begin{array}{*{20}{c}}
{C{H_3}\,\,\,\,\,\,\,\,} \\
{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\
{C - C{H_3}} \\
{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\
{Cl\,\,\,\,\,\,\,\,\,\,\,\,\,\,}
\end{array}$ - D$\begin{array}{*{20}{c}}
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{H_3}C} \\
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|} \\
{C{H_3} - CH - CH} \\
{\,\,\,\,\,\,\,\,\,\,|\,\,\,\,\,\,\,\,\,\,\,\,\,\;\;|} \\
{\,\,\,\,\,\,\,Cl\,\,\,\;{H_3}C}
\end{array}$
