Hybrid Orbitals?

Question

If you have a structure how can you determine if it's bonds are sp, sp2, or s. Is it based on sigma bonds? I hope the question makes sense.

Answer 1

its based on p orbitals

so if you have a carbon holding 4 things apart its sp3 hybridized
example CH3CH3 the carbon-carbon bond is sp3

if you have carbon holding 3 things apart CH2=CH2 its sp2 hybridized

if you have carbon holding 2 things apart CH triple conded to CH its sp hybridized

hope that helped

Answer 2

Count the total number of bonding "regions". A double bond, single bond, triple bond are all counted as 1 "region", for the purposes of this excercise. Lone pairs do not count as a region; ignore any lone pairs. After counting the total # of regions, use the following chart to see what hybridization you have:

Regions Hybridization
2 sp
3 sp2
4 sp3
5 sp3d
6 sp3d
7 sp3d2

Hope that helps!

Answer 3

we can determine its structure by calculating no.of sigma bonds and no. of lone pairs present in that compound.
if the total is equal to 2 then the compound is SP hybridized
3=SP^2
4=SP^3 AND FOR D-BLK. ELEMENTS ITS DSP^2
5=SP^3D
6=SP^3D^2
7=SP^3D^3
