Geometrical isomerism is not shown by

• A

  
  
  
• B

  
  
  
• Correct answer
  C

  $\mathrm{CH}_2=\mathrm{C}(\mathrm{Cl}) \mathrm{CH}_3$
• D

  $\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}_2$

Solution

The condition for geometrical isomerism is


$\mathrm{CH}_2=\mathrm{C}(\mathrm{Cl}) \mathrm{CH}_3$ does not follow above mention condition.

Hence, the correct answer is option: 'C'.
