Question

Assertion: Calcium carbide on hydrolysis gives ethylene.
Reason: Calcium carbide contains $C^{4-}$ anions.

• A. If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:
• B. If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:
• C. If Assertion: is true but Reason: is false
• D. If both Assertion: and Reason: are false

Answer 1

Answer: (C)

$CaC _{2}+2 H _{2} O \longrightarrow Ca ( OH )_{2}+\underset{\text { acetylene }}{ C _{2} H _{2}}$ Calcium carbide contains $C _{2}^{2-}$ anion. Hence, Reason is false.
