Question
An industrial method of preparation of methanol is :
A.
catalytic reduction of carbon monoxide in presence of $$ZnO - C{r_2}{O_3}$$
B.
by reacting methane with steam at 900°C with a nickel catalyst
C.
by reducing formaldehyde with lithium aluminium hydride .
D.
by reacting formaldehyde with aqueous sodium hydroxide solution
Answer :
catalytic reduction of carbon monoxide in presence of $$ZnO - C{r_2}{O_3}$$
Solution :
\[\underbrace{CO+{{H}_{2}}}_{\text{water gas}}+{{H}_{2}}\xrightarrow[{{300}^{\circ }}C]{C{{r}_{2}}{{O}_{3}}-ZnO}\underset{\text{Methanol}}{\mathop{C{{H}_{3}}OH}}\,\]
