Group 15 Flashcards
What are the properties of group 15 elements?
There is a lone pair of electrons, they act as Lewis bases and they are electron rich.
What is the bonding in N2?
N-triple bond-N
What is the structure of P4?
60 degree bond angles, weird diamond shape thing.
Why does N2 have an unreactive triple bond?
There is a large HOMO/LUMO gap so oxidation and reduction is prevented.

120pm.
What is the bond length on N2O4?
121pm.
How is P4O10 formed?
The reaction of P4 and O2.
What is the structure of P4O10?
It is a caged structure.
What does P4O6 react with water to give?
