Isomerism which is present only in alkene is
Correct answer: C. cis-trans isomerism
- A. structural isomerism
- B. metamerism
- C. cis-trans isomerism
- D. no such process occurs
Explanation
Cis-trans isomerism, also known as geometric isomerism, is a type of stereoisomerism that is characteristic of alkenes. It arises due to the restricted rotation about the carbon-carbon double bond, leading to different spatial arrangements of substituents. Molecules with the same atomic formula but different spatial arrangements of groups around the double bond are called cis and trans isomers. This isomerism is unique to alkenes because the presence of a double bond prevents free rotation, allowing distinct spatial configurations based on the location of substituents around the double bond.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
