Question

Isomerism that arises out of the difference in spatial arrangement of atoms or groups about the doubly bonded carbon atoms are called?

• A. Structural Isomerism
  
• B. Position Isomerism
  
• C. Geometrical Isomerism
  
• D. None of the above

Answer 1

The correct option is C Geometrical Isomerism


The restricted rotation of an atom or groups around the doubly bonded carbon gives different geometries of a compound. Such compounds are called geometrical isomers. They differ in spatial arrangement from one another.
Geometrical Isomerism are also called as cis-trans Isomersim.
