MCQ
In the given reaction,
CH2 = CH2(g) + H2(g) → CH3—CH3(g)
ethene undergoes:
CH2 = CH2(g) + H2(g) → CH3—CH3(g)
ethene undergoes:
- AReduction process.
- BOxidation process.
- CAddition process.
- DAll of these.
✓
Answer
- Reduction process.
Explanation:
CH2=CH2 + H—H → H3C—CH3
(Addition of hydrogen)
Because of the addition of hydrogen, there occurs reduction of ethylene.
