Current Question (ID: 21249)

Question:

$\text{Out of the following, the alkene that exhibits optical isomerism is:}$ $1. \text{ 2-Methyl-2-pentene}$ $2. \text{ 3-Methyl-2-pentene}$ $3. \text{ 4-Methyl-pentene}$ $4. \text{ 3-Methyl-1-pentene}$

Options:

1. $\text{2-Methyl-2-pentene}$
2. $\text{3-Methyl-2-pentene}$
3. $\text{4-Methyl-pentene}$
4. $\text{3-Methyl-1-pentene}$

Solution:

$\text{Hint: An asymmetric carbon atom must be present in the molecule.}$ $\text{Explanation:}$ $\text{Optical isomerism occurs when substances have the same molecular formula and structural formula, but one cannot be superimposed on the other.}$ $\text{It is exhibited by asymmetric molecules, also known as chiral molecules, that have at least one asymmetric carbon atom. An asymmetric carbon atom is bonded to four different atoms or groups.}$ $\text{The structures of given alkenes are as follows:}$ $\text{The molecule 3-methyl-1-pentene has one asymmetrical carbon atom (marked by *) and thus it will exhibit optical isomerism.}$ $\text{Hence, option 4 is the correct answer.}$
