Chemical Bonding and Molecular Structure Part 1

N3−is linear species.Hybridisation = Number of sigma bond + number of lone pairs + number of coordinate bonds.
Hybridisation of N in NO=1+1+1=3. So, hybridisation is sp2 and structure is bent or V-shape.
Hybridisation of O in OCl2=2+2=4. So, hybridisation is sp3 and structure is bent or V-shape.
Hybridisation of O in O3=1+1+1=3. So, hybridisation is sp2 and structure is bent or V-shape. linear.
