Question

The double bond in $C_2$, on the basis of $MOT,$ Consists of-

• A. One $\sigma$ and one $\pi$ bond
• B. Two $\sigma$ bond
• C. Two $\pi$ bond
• D. One Covalent and one ionic bond

Answer 1

Answer: (C)

The valence electrons, responsible for bond formation occupy $\pi$ molecular orbitals, so both bonds are $\pi$ bonds in $C_2$.



These two marked $\pi$ molecular orbitals are filled, so both the bonds are $\pi$ bonds.
