Current Question (ID: 8096)

Question:

$\text{A diatomic molecule, among the following species, that only has } \pi \text{ bonds according to the Molecular Orbital Theory (MOT) is:}$

Options:

1. $\text{Be}_2$
2. $\text{O}_2$
3. $\text{N}_2$
4. $\text{C}_2$

Solution:

$\text{HINT: } \text{C}_2 \text{ only contains pi bonds.}$ $\text{Explanation:}$ $\text{The MOT diagram of a } \text{C}_2 \text{ molecule is as follows:}$ $\text{In } \text{C}_2 \text{ molecule, bonding electrons are present in } \pi_{2p} \text{ molecular orbitals. The bonds are formed by } \pi_{2p} \text{ molecular orbitals only. So, } \text{C}_2 \text{ has } 2\pi \text{ bonds.}$
