The number and type of bonds in ion in $\mathrm{CaC}_{2}$ are:

The number and type of bonds in ion in $\mathrm{CaC}_{2}$ are:
  1. One $\sigma$ bond and one $\pi$ -bond
  2. One $\sigma$ bond and two $\pi$ -bond
  3. Two $\sigma$ bond and two $\pi$ -bond
  4. Two $\sigma$ bond and one $\pi$ -bond

Solution

The structure of $\mathrm{CaC}_{2}$ is $\mathrm{Ca}^{2+}[: \mathrm{C} \equiv \mathrm{C}:]^{2}-$
i.e, one $\sigma$ and two $\pi$ bonds *
