Which of the following does not show geometrical isomerism?
Correct answer: C. 1, 1 - dichloro - 1 - pentene
- A. 1, 2-dichloro -1 - pentene
- B. 1, 3 - dichloro - 2 - pentene
- C. 1, 1 - dichloro - 1 - pentene
- D. 1, 4 - dichloro - 2 - pentene
Explanation
In geometrical isomerism,the atoms are bonded by a double bond that does not rotate but it can also happen because of the ring structure. In 1,1-dichloro -2-pentene at least two groups or atoms attached to doubly bonded carbon atoms should be different. Reference:google

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
