Commercially methanol is prepared by

A

Reduction of CO in presence of ZnO⋅Cr2O3\mathrm { ZnO } \cdot \mathrm { Cr } _ { 2 } \mathrm { O } _ { 3 }

B

Methane reacts with water vapours at 900∘C900 ^ { \circ } \mathrm { C } in presence of Ni catalyst

C

Reduction of HCHO by LiAlH4\mathrm { LiAlH } _ { 4 }

D

Reduction of HCHO by aqueous NaOH

Answer

Reduction of CO in presence of ZnO⋅Cr2O3\mathrm { ZnO } \cdot \mathrm { Cr } _ { 2 } \mathrm { O } _ { 3 }

Explanation

Solution

CO+H2CuO−ZnO−Cr2O3573 K,200 atmCH3OH Methanol \mathrm { CO } + \mathrm { H } _ { 2 } \frac { \mathrm { CuO } - \mathrm { ZnO } - \mathrm { Cr } _ { 2 } \mathrm { O } _ { 3 } } { 573 \mathrm {~K} , 200 \mathrm {~atm} } \underset { \substack { \text { Methanol } } } { \mathrm { CH } _ { 3 } \mathrm { OH } }
