What type of reaction occurs between ethene and hydrogen?
Correct answer: A. Addition
- A. Addition
- B. Neutralization
- C. Dehydration
- D. Oxidation
Explanation
When ethene reacts with hydrogen, an addition reaction occurs where the unsaturated ethene molecule becomes saturated with the addition of hydrogen atoms, forming ethane (C2H6).The other options are incorrect because neutralization involves acids and bases, dehydration involves the removal of water, and oxidation involves the removal of hydrogen, none of which are applicable to the specific reaction between ethene and hydrogen.
