The correct option is
C sp
3, sp
3, sp
2Let's take a look at the electronic configuration of carbon:
Now, in case of
CH4
Four
sp3 hybrid orbitals are formed,
Which will combine with four hydrogen atoms Hybridization
⟹ sp3 [One s-orbital Three p-orbitals]
Now, in case of
C2H6 ⟹
It is two
CH3 bonded together.
What is the bond between two carbon atoms?
Let’s take a look.
Four
sp3 hybrid orbitals are formed.
One
sp3 hybrid orbital will combine with
sp3 hybrid orbital of other carbon. (σ bond)
Three
sp3 hybrid orbitals will combine with three hydrogen for each carbon Hybridization
⟹ sp3 [ one s-orbital, three p-orbitals]
Now, in case of
C2H4
Three
sp2 hybrid orbitals are formed.
In this case, what is the bond between two carbon atoms??
Let's take a look:
Three
sp2 hybrid orbitals are formed.
One orbital containing one electron will form
π bond with the other carbon atom.
Three
sp2 orbitals will form
σ bonds with hydrogen and
σ bond with the other carbon.
⟹ Therefore, there will be two bonds between two carbons (one
σ and one
π)
Hybridization
⟹ sp2 [one s-orbital, two p-orbitals]
CH4 ⟹
C2H6 ⟹
C2H2 ⟹
