Ethene reacts with Oxygen in the presence of silver oxide to produce _.

Correct answer: B. Ethylene epoxide

  • A. Ethylene glycol
  • B. Ethylene epoxide
  • C. Methylene oxide
  • D. Both Options A and B are correct

Explanation

Alkenes are capable of reacting with oxygen in the presence of elemental silver to form a series of cyclic ethers called epoxides. Epoxides are three-atom cyclic systems in which one of the atoms is oxygen. The simplest epoxide is epoxyethane (Ethylene oxide).Attached below is a picture, summarizing the process; QUESTION NUMBER 119

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.
