Current Question (ID: 21313)

Question:

$\text{The compound among the following that shows geometrical isomerism is:}$ $1.\ \text{1-Phenyl-2-butene}$ $2.\ \text{3-Phenyl-1-butene}$ $3.\ \text{2-Phenyl-1-butene}$ $4.\ \text{1,1-Diphenyl-1-propene}$

Options:

1. $\text{1-Phenyl-2-butene}$
2. $\text{3-Phenyl-1-butene}$
3. $\text{2-Phenyl-1-butene}$
4. $\text{1,1-Diphenyl-1-propene}$

Solution:

$\text{Hint: If double bonded carbon contains same atoms or groups hence, compound will not show geometrical isomerism.}$ $\text{The geometrical isomerism arises when atoms or groups are arranged differently in space due to restricted rotation of a bond or bonds in a molecule.}$ $\text{The example of geometrical isomerism is as follows:}$ $\text{Cis: } \text{H}_3\text{C} - \text{CH} = \text{CH} - \text{CH}_3$ $\text{Trans: } \text{H}_3\text{C} - \text{CH} = \text{CH} - \text{CH}_3$ $\text{The structure of the given compounds in the options are as follows:}$ $\text{Only 1-phenyl-2-butene shows geometrical isomerism. The structures are as follows:}$
