Based on hybridisation theory, the hybridisation states of the atoms are $\mathrm{sp}$, $\mathrm{sp}$ and $\mathrm{sp^3}$, for the atoms N, N and O, which are connected to each other in this order: Conventionally, as most textbooks suggest, hybridisation states are derived from electronic geometry of the atoms (i.e. I'm now reading about Bent's rule... there's a lot to take in / relearn here. Total valance electrons pairs = σ bonds + π bonds + lone pairs at valence shells. how the electron density regions are arranged around the atoms). A few notes (please correct me if needed)... if I understand this, the method I described above (and is used in a majority of places if I search) is outdated? In that line you 1. draw a proper Lewis representation (possibly even some mesomeric forms) 2. apply VSEPR and 3. then explain it using hybridisation. The exponents on the subshells should add up to the number of bonds and lone pairs. Can I hang this heavy and deep cabinet on this wall safely?

Many students face problems with finding the hybridization of given atom (usually the central one) in a compound and the shape of molecule. The sp² orbitals for such atoms used to be part of a VB description, but (at the latest) with the formulation of Bent's rule that basically became obsolete. Look at bonding & lone pairs on each atom. Why the sum of two absolutely-continuous random variables isn't necessarily absolutely continuous? Side remark: MOT does not use or need hybridisation. In this section, we will basically understand the formation of water on the basis of hybridization. I also read the topic in my book but this issue wasn't addressed there too. Okay, back to nitpicking: The only correct way to use hybridisation is to use it post-geometry determination (so it's not only practically incorrect). What is Hybridization? Nitrogen dioxide is a chemical compound with the formula NO 2.It is one of several nitrogen oxides. First, find the most likely structure with the correct number of bonds, then deduce the hybridisation. of monovalent atom around the central atom.
