CaC 2+2 H 2 O longrightarrow Ca ( OH )2+ underset text acetylene C 2 H 2 Calcium carbide contains C 22- anion. Hence, Reason is false.

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

If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:

If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:

If Assertion: is true but Reason: is false

If both Assertion: and Reason: are false

$C a C_{2} + 2 H_{2} O ⟶ C a (O H)_{2} + acetylene C_{2} H_{2}$ Calcium carbide contains $C_{2}^{2 -}$ anion. Hence, Reason is false.
