Question

On hydrolysis, aluminium carbide produces

• A. CH₄ 
• B. C₂H₆ 
• C. C₂H₄
• D. C₂H₂ 

Hint:

Always remember that the products of hydrolysis reactions depend on the nature of the compound being hydrolyzed. Aluminium carbide produces methane gas upon hydrolysis.

Answer 1

The Correct Option is A

Step 1: Understanding the Reaction.
Aluminium carbide reacts with water (hydrolysis) to produce methane gas (CH4). The chemical reaction for the process is: \[ \text{Al}_4\text{C}_3 + 12 \text{H}_2\text{O} \rightarrow 4 \text{Al(OH)}_3 + 3 \text{CH}_4 \] Thus, methane (CH4) is produced.

Step 2: Analyzing the options.
(A) CH4: Correct — This is the product of the hydrolysis reaction.
(B) C2H6: Incorrect — Ethane is not produced in this reaction.
(C) C2H4: Incorrect — Ethene is not produced either.
(D) C2H2: Incorrect — Acetylene is not a product of this reaction.

Step 3: Conclusion.
The correct answer is (A) CH4 as methane is produced during the hydrolysis of aluminium carbide.
