Question

Which of the following compounds will show cis-trans isomerism?

विकल्प

• (CH₃)₂C = CH-C₂H₂

• H₂C = CCl₂

• CH₃HC = CCl CH₃

• HClC = CH₂

Answer 1

CH₃HC = CCl CH₃ 

Explanation:

\[\begin{array}{cc}
\phantom{}\ce{CH3}\phantom{........}\ce{Cl}\phantom{}\\
\phantom{..}\backslash\phantom{......}/\phantom{}\\
\phantom{..}\ce{C = C}\\
\phantom{..}/\phantom{......}\backslash\phantom{}\\
\phantom{}\ce{\underset{trans-2-chlorobut-2-ene}{\phantom{....}H\phantom{........}CH3}}\phantom{}
\end{array}\]

\[\begin{array}{cc}
\phantom{..}\ce{CH3}\phantom{........}\ce{CH3}\phantom{}\\
\phantom{..}\backslash\phantom{......}/\phantom{}\\
\phantom{..}\ce{C = C}\\
\phantom{..}/\phantom{......}\backslash\phantom{}\\
\phantom{}\ce{\underset{cis-2-chlorobut-2-ene}{\phantom{....}H\phantom{........}Cl}}\phantom{..}
\end{array}\]
