Show Answer
Answer:
Correct Answer: B
Solution:
Phoron $ \begin{matrix} CH_3 \\ CH_3 \\ \end{matrix}>C=O+H_2CH-\overset{\overset{O}{\mathop{||}}}{\mathop{C}}-CHH_2+O=C<\begin{matrix} CH_3 \\ CH_3 \\ \end{matrix} $
$ \underset{-2H_2O}{\mathop{\xrightarrow{\text{Dry }HCl}}} $
$ \begin{matrix} CH_3 \\ CH_3 \\ \end{matrix}>\underset{Phoron}{\mathop{C=CH-\overset{\overset{O}{\mathop{||}}}{\mathop{C}}-CH}}=C<\begin{matrix} CH_3 \\ CH_3 \\ \end{matrix} $
