Correct answer: C. Different
- A. Same
- B. Identical
- C. Different
- D. None of these
Explanation
The necessary and sufficient condition for a compound to exhibit geometric isomerism is that the two groups attached to the same carbon must be different. To get geometric isomers you must have:restricted rotation(often involving a carbon-carbon double bond for introductory purposes ); two different groups on the left-hand end of the bond and two different groups on the right-hand end.

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.
