Question

The isomerism that arises due to restricted bond rotation is:

• A. metamerism
• B. optical Isomerism
• C. position isomerism
• D. geometrical isomerism
• E. chain isomerism

Answer 1

Answer: (D)

geometrical isomerism

Geometrical isomers occur where you have restricted rotation somewhere in a molecule. These isomers occur where you have restricted rotation somewhere in a molecule. One form is converted to another only by removing respective atoms from its position not by simply rotating due to restricted bond rotation.
