Q. The number of types of bonds between two carbon atoms in calcium carbide is
A) One sigma, two pi
B) One sigma, one pi
C) Two sigma, one pi
D) Two sigma, two pi
Explanation
(a)
$CaC_{2} \rightleftharpoons \ Ca^{2 +} + \ C_{2}^{2 -}\$
Carbide ion
In carbide ion, two carbon atoms are joined by triple bond
(If is isoelectronic with $N_{2}$)
$- C \equiv C -$
with two $\pi$ and one $\sigma$-bonds.
