Question
The carbide which does/do not give propyne on hydrolysis is/are :
Options
A.Al4C3
B.CaC2
C.Fe3C
D.Mg2C3
Solution
(A) Al4C3 + 12 H2O → 4Al(OH)3 + 3CH4
(B) CaC2 + 2 H2O → Ca(OH)2 + C2H2
(C) Does not give any gas.
(D) Mg2C3 + 4H2O → 2Mg(OH)2 + CH3 − C ≡ CH.
(B) CaC2 + 2 H2O → Ca(OH)2 + C2H2
(C) Does not give any gas.
(D) Mg2C3 + 4H2O → 2Mg(OH)2 + CH3 − C ≡ CH.
