Which of the following is/are basic conditions for geometric isomerism?
Correct answer: D. Both A and B
- A. Having carbon-carbon double bond (C = C)
- B. Different groups are attached with carbon-containing double bond
- C. Double bond involves free rotation
- D. Both A and B
Explanation
Two conditions must be met for a molecule to exhibit geometric isomerism. First, there must be restricted rotation, typically due to a carbon-carbon double bond or a ring structure. Second, each carbon atom involved in the restricted rotation must be bonded to two different groups.

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.
