To determine which compound shows geometrical isomerism, we need to understand what geometrical isomerism is. Geometrical isomerism, also known as cis-trans isomerism, is a type of stereoisomerism that occurs in alkenes and other compounds wherein geometry or the spatial arrangement of atoms or groups around a double bond can result in different isomers.
For a compound to show geometrical isomerism, the following conditions must be met:
Let's analyze the given options:




Option 3, represented in Fig 3, satisfies the conditions for geometrical isomerism, where different groups are attached to the carbons of a double bond, allowing cis-trans isomers.
Conclusion: The correct answer is option 3.
The compound in option (3) shows geometrical isomerism due to the unsymmetrical arrangement around the double bond.
The Correct Answer is: 
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)
