Geometric isomerism is shown by:
Correct answer: B. Alkenes
- A. Alkanes
- B. Alkenes
- C. Alkynes
- D. All of the above options are correct
Explanation
Geometric Isomerism results most commonly from C=C. The important property which introduces the feature is the inability of the Carbon atoms to rotate relative to one another about the double bond.

About Alkenes
Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond with sigma and pi components and restricted rotation. Their reactions include electrophilic addition of hydrogen, halogens, hydrogen halides and water, with Markovnikov orientation, oxidation, combustion and polymerisation, while their preparation commonly involves elimination from alkyl halides or alcohols.
