N-n bond is weaker than p-p bond
WebJan 7, 2024 · The oxygen atom is larger than the hydrogen, fluorine, while the phosphorus atom is larger than hydrogen, fluorine, and beryllium. Thus, I would imagine that the sigma orbital overlap would be weaker due to a … WebThe bond length of the N-N bond is smaller than that of the P-P bond. Due to this, the four non-bonding electrons of the two nitrogen atoms repel each other making the bond weaker. This does not happen in the case of phosphorus because P-P bond length is more. So, the repulsion of non-bonding electrons is lesser than in N-N.
