Question

What is the hybridisation of N in NO and NO2?

Answer 1

X=( 5 +0+0)/2
This comes out to be 2.5.... Now in order to get the hybridization as a whole number we have to comapare the electronegativity of the central atom (nitrogen here) with the side atoms (oxygen here). When side atom is more electronegative than X’=X+0.5 and when central atom is more electronegative than X’=X-0.5……

SO HYBRIDIZATION OF NO2 is 3

Similarly the hybridisation of NO is also 3 i.e. sp2
hope it helps:)
