wiki pe to nahin mila
1to find the hybridization state of any compound all you have to do is predict the sigma bonds and lone pair in central atom.
ex.
CO2 σ.b.=2 l.p.=0. h.s.=2+0=2=sp
XeF6 σ.b.=6 l.p.=1 h.s.=6+1=7=sp3d3
BH3→NH3 for B .σ b.=4 l.p.=0 h.s.=4+0=4=sp3
for N .σ b.=4 l.p=0 as the lone pair is shared with B a sigma bond is formed and lone pair is lost. h.s.=4+0=4=sp3.
11for N .σ b.=4 l.p=0 as the lone pair is shared with B a sigma bond is formed and lone pair is lost. h.s.=4+0=4=sp3.
N ke 4 σ KAISE??
62arrey yar is simple rule ka bhee naam hai :(
ye to aise hi pata hota hai na
count the number of lone pairs + number of bond pairs
if 2 bonds then SP
3 sp2
4 sp3
5 sp3d
and so on...
