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)	$M{o}_2{O}_3/\Delta$	$(C{H}_{3}COO{)}_{2}Mn/\Delta$	$Cu/523K/100atm$
(b)	$Cu/523K/100atm$	$M{o}_2{O}_3/\Delta$	$(C{H}_{3}COO{)}_{2}Mn/\Delta$
(c)	$(C{H}_{3}COO{)}_{2}Mn/\Delta$	$Cu/523K/100atm$	$M{o}_2{O}_3/\Delta$
(d)	$M{o}_2{O}_3/\Delta$	$Cu/523K/100atm$	$(C{H}_{3}COO{)}_{2}Mn/\Delta$

• A. a
• B. b
• C. c
• D. d

Answer 1

Answer: (B)

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

$C{H}_3-H\underset{\text{/ 100 atm}}{\overset{\text{Cu[O]/523K}}{\to }}C{H}_3-OH$

Methane show partial oxidation into methanal in presence of $M{n}_2{O}_3/\Delta$ catalyst.



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