Question

Which of the following is obtained on the reaction of water with aluminium carbide?

Options

• Methane

• Ethane

• Ethene

• Ethyne

Answer 1

Methane

Explanation:

When aluminium carbide (Al₄C₃) reacts with water (H₂O), it undergoes hydrolysis to release methane gas and form aluminium hydroxide. This is a common laboratory method to produce methane:

\[\ce{Al4C3 + 12H2O -> 4Al(OH)3 + 3CH4 ^}\]
