Select one which shows cis-trans isomerism.
Correct answer: C. ClCH=CHCl
- A. Cl2C=CCl2
- B. CH2=CH2
- C. ClCH=CHCl
- D. Br2C=CBr2
Explanation
ClCH=CHCl is correct for showing cis-trans isomerism because it has two different substituents attached to the carbon atoms of the double bond. In this molecule, there are two possible arrangements of the chlorine atoms relative to each other across the double bond, resulting in cis and trans isomers.

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.
