Electron dot structure of
N2O molecule
First draw the main skeleton structure of
N2O having N-N-O connectivity with single bonds without showing any formal charge, that is,
Total number of valence electrons
=(5×2)+(6×1)=16e−s Four electrons are used to form two bonds in the skeleton structure
Remaining valence electrons
=16−4=12 The central nitrogen atom needs two more lone pairs, terminal nitrogen atom needs three more lone pairs and oxygen atom needs three more lone pairs to complete their octet.
Therefore, total 16 electrons are needed. But we have 12 electrons.
Hence, 2 additional bonds are formed, which can be placed in three different ways,
The most appropriate structure of
N2O is
The resonating structures of
N2O are as follows:
