Which gas is evolved when calcium carbide (CaC2) reacts with water?
A. Methane
B. Ethylene
C. Acetylene✓ Correct Answer
D. Ethane
💡 Solution & Explanation
When calcium carbide reacts with water, it undergoes a rapid hydrolysis reaction to produce flammable acetylene gas along with calcium hydroxide precipitate. Alternative hydrocarbons like methane or ethane are generated through different chemical synthesis routes rather than carbide hydrolysis. Chemical reactions and their gaseous products are common topics in general science multiple-choice questions.
