Asked in Premeth Test 15 — Organic Chemistry Concepts and Hydrocarbons (17 March 2025) 2025Moderate

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

Correct answer: C. Geometrical Isomerism

  • A. Structural Isomerism
  • B. Stereo Isomerism
  • C. Geometrical Isomerism
  • D. Optical Isomerism

Explanation

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 Isomerism.

About Isomerism

Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
