what is the shape of sp² hybridisation?

Q- what is the shape of sp² hybridisation?

Ans- shape of any compound depends upon bond pair available in given compound.

Hybridization shows total number of bond pair and lone pair in any compound.

We find hybridization of any given compound by the following process.

Let's find-

given compound-SO3

Central atom of compound-S

Velency of central atom-6

Here is a  formula to know the hybridization of any compound

Z=1/2{central atom's velency+ (-ve charge)-(+ve charge)+no.of monovalent atom }

(Z=sum of bond pair & lone pair)

Z=1/2(6)

  =3

lone pair=z-no. Of surrounding atom

               =3-3=0

According to VSPER theory 

Z=3, then hybridization is sp²

And geometry is trigonal planer.

There is another condition if there is lone pair available in given compound? 

Let's find-

Given compound-SO2

Central atom of compound-S

Velency of central atom-6

Z=1/2{central atom's velency+ (-ve charge)-(+ve charge)+no.of monovalent atom }

Z=1/2(6)

   =3

lone pair=z- no.of surrounding atom

               = 3-2

               =1

Z=3then hybridisation is sp²

Geometry=trigonal planer

But shape is Bent/angular/V shape
