In these cases, I would tend to go with ‘unhybridised’ until an experimental or calculative result proves me wrong. For 4 electron density regions, it is $\mathrm{sp^3}$-hybridised etc. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. From the Lewis structure I have drawn, we can derive the results as such. This can be done directly from the Lewis diagram using VSEPR theory. I am/ was a bit hesitant to up-vote this, but given the two wrong answers, this is much better. First, find the most likely structure with the correct number of bonds, then deduce the hybridisation. I also read the topic in my book but this issue wasn't addressed there too. (3 $\times$ sp2 orbitals and 1 $\times$ p orbital). HOPE IT HELPS!

Many students face problems with finding the hybridization of given atom (usually the central one) in a compound and the shape of molecule. NO 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers.At higher temperatures it is a reddish-brown gas. We can tell by the type of bonds that we again need two unhybridised $\mathrm p$ orbitals on the end atoms (remember that the orientations of the double bonds are equivalent!) Colleagues don't congratulate me or cheer me on when I do good work. During pre-hybridization put 200 µl of hybridization buffer with dextran sulfate into each well of a 96-well plate using multichannel pipette.
