When a mixture of gas X and Y is compressed to 300 atm pressure and then passed over a catalyst consisting of a mixture of zinc oxide and chromium oxide (heated to a temperature of 300$℃$ ), then an organic compound Z having the molecular formula ${\mathit{CH}}_{4}O$ is formed. The name of gas X is:

When a mixture of gas X and Y is compressed to 300 atm pressure and then passed over a catalyst consisting of a mixture of zinc oxide and chromium oxide (heated to a temperature of 300$℃$ ), then an organic compound Z having the molecular formula ${\mathit{CH}}_{4}O$ is formed. The name of gas X is carbon monoxide.
Carbon monoxide and hydrogen are compressed to 300 atm pressure and then passed over a catalyst consisting of a mixture of zinc oxide and chromium oxide. The organic compound Z formed is methanol $\left({\mathit{CH}}_3\mathit{OH\; or }{\mathit{CH}}_{4}O\right)$. Carbon monoxide is a highly poisonous gas.

Its reaction is given as
$\mathit{CO}+2H_2\to C{H}_3\mathit{OH}$
