H₂O + C → H₂ + CO
The above reaction is an example of:
- AZiegler–Natta process
- BWater gas reaction
- CAldol condensation
- DWacker process
Show answer and explanation
Correct answer: (b) Water gas reaction
Explanation
When steam is passed over red-hot coke (carbon), it gives a mixture of carbon monoxide and hydrogen:
- C + H₂O → CO + H₂
This mixture is called water gas (or synthesis gas), and the reaction is the water gas reaction. Water gas is a fuel and a source of hydrogen.
- The Ziegler–Natta process makes polymers such as polythene.
- Aldol condensation joins aldehydes or ketones.
- The Wacker process turns ethene into acetaldehyde.
