Question

What is X in the following reaction? \[ CO(g) + 2H_2(g) \xrightarrow{X} CH_3OH(l) \]

• A. \( \text{Co} \)
• B. \( \text{Mg/dry ether} \)
• C. \( \text{Na} \)
• D. \( \text{Mo}_2\text{O}_3 \)

Hint:

For hydrogenation reactions such as this one, Co (Cobalt) is a commonly used catalyst.

Answer 1

The Correct Option is A

Step 1: The reaction represents the formation of methanol from carbon monoxide and hydrogen gas, a reaction known as the "water gas shift reaction". The catalyst used to promote this reaction is typically cobalt (Co), which facilitates the conversion of carbon monoxide and hydrogen to methanol.
Step 2: Therefore, in the given reaction, \( X \) is cobalt (Co).
