Question

Identify the correct catalyst and reaction conditions for the controlled oxidation of methane to (i) methanol $(X)$, (ii) methanal $(Y)$ and ethane to (iii) ethanoic acid $(Z)$.

	(X)	(Y)	(Z)
(a)	$Mo_2O_3/\Delta$	$(CH_3COO)_{2} Mn/\Delta$	$Cu/523 K/100 \,atm$
(b)	$Cu/523K/100\,atm$	$Mo_2O_3/\Delta$	$(CH_3COO)_2\,Mn/\Delta$
(c)	$(CH_3COO)_2\,Mn/\Delta$	$Cu/523 K/100\, atm$	$Mo_2O_3/\Delta$
(d)	$Mo_2O_3/\Delta$	$Cu/523 K/100\,atm$	$(CH_3COO)_{2} Mn/\Delta$

• A. a
• B. b
• C. c
• D. d

Answer 1

Answer: (B)

Methane oxidise into methanol by controlled oxidation in presence of catalyst $Cu/523K/100\,atm$

$CH_3-H \ce{ ->[{Cu[O]/523\,K}][{/ 100 atm}] }CH_3-OH$

Methane show partial oxidation into methanal in presence of $Mn _{2} O _{3} / \Delta$ catalyst.



Ethane oxidise in presence of $Mn ^{+2}$ catalyst (in acetic acid solution) into ethanoic acid.
