Current Question (ID: 21333)

Question:

$\text{Geometrical isomerism is not shown by:}$ $1.\ 1,1\text{-Dichloro-1-pentene}$ $2.\ 1,2\text{-Dichloro-1-pentene}$ $3.\ 1,3\text{-Dichloro-2-pentene}$ $4.\ 1,4\text{-Dichloro-2-pentene}$

Options:

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

Solution:

$\text{Hint: At least two groups or atoms attached to doubly bonded carbon atoms should be different}$ $\text{Cis–trans isomerism, also known as geometric isomerism, is a term used in organic chemistry.}$ $\text{If doubly bonded carbon atoms contain the same atom or group of atoms, the compound will not show cis-trans isomerism.}$ $\text{The structures of the given compound are as follows:}$ $\text{All have different groups or atoms around double bond carbon atom.}$ $\text{But in the case of 1,1-dichloro-1-pentene two Cl atoms are attached to the doubly bonded carbon atom.}$ $\text{Hence it will not show geometrical isomerism.}$
