Ethene is the first member of __________?
Correct answer: A. Alkenes Family
- A. Alkenes Family
- B. Saturated hydrocarbon
- C. Aromatic hydrocarbon
- D. None of These
Explanation
Ethene, C2H4, contains a carbon-carbon double bond and is the simplest member of the alkene homologous series. Alkenes are unsaturated hydrocarbons with the general formula CnH2n for open-chain members. Students may select saturated hydrocarbon because ethene contains only carbon and hydrogen, but the double bond makes it unsaturated.

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.
