Vedclass · Answer

(B) The calcium carbide $(CaC_2)$ molecule consists of a $Ca^{2+}$ ion and a carbide ion $(C_2^{2-})$.In the carbide ion $(C_2^{2-})$,the two carbon atoms are connected by a triple bond.$A$ triple bond consists of one sigma $(\sigma)$ bond and two pi $(\pi)$ bonds.Therefore,the number and type of bonds between the two carbon atoms are one $\sigma$ bond and two $\pi$ bonds.

The number and type of bonds between two carbon atoms in $CaC_2$ are
