Name the catalyst [X] for the reaction: Co(g)+H2(g)[X]→HCHO(g)

The correct option is B CuCO(g)+H2(g)[X]→HCHO(g)Here, X is copper (Cu), which acts as a good reductant and gives formaldehyde in this reaction. The reaction intact, occurs in the following manner CO(g)+H2(g)→CH3OHCu→HCHO

Name the catalyst [X] for the reaction:
$C o (g) + H_{2} (g) [X] \to H C H O (g)$

The correct option is B $C u$
$C O (g) + H_{2} (g) [X] \to H C H O (g)$
Here, X is copper (Cu), which acts as a good reductant and gives formaldehyde in this reaction. The reaction intact, occurs in the following manner
$C O (g) + H_{2} (g) \to C H_{3} O H C u \to H C H O$
