Question

__________ is prepared on a large scale from water gas.

• A. Methanol
• B. Ethanol
• C. Methane
• D. Ethane

Answer 1

The correct option is A Methanol

Methanol is prepared on a large scale from water gas.
Water gas is an equimolar mixture of $CO$ and $H_2$. Water gas is heated with hydrogen (2:1 ratio) in presence of catalyst to form methanol.
$\underset{\text{synthetic gas}}{\underset{\text{Water gas}}{CO+H_2}}+H_2\underset{{300}^{o}C\text{under pressure}}{\overset{C{r}_2{O}_3-ZnO}{\to }}C{H}_3-OH$
