WebJul 8, 2024 · The π bond in N = N is actually not stronger than the σ bond. Rather the σ bond is stronger in N = N than in N − N, and this plus the π bond gives the double-bonded linkage more than twice the binding energy. So what makes the N = N σ bond stronger? Web1 Answer Sorted by: 8 Due to larger atomic size $\ce {P}$ is unable to form pi bonds and so it is tetra-atomic in which each $\ce {P}$ atom is linked with 3 other $\ce {P}$ atoms by 3 sigma bond. But, due to smaller atomic size $\ce {N}$ forms 1 sigma and 2 pi bonds i.e. triple bonds with other $\ce {N}$ atom and exists as diatomic molecule.
