s - character in sp3 hybridization is
Here:
1s orbital + 1p orbital ⇒ 2 sp hybrid orbitals
1s orbital + 2p orbital ⇒ 3 sp2 hybrid orbitals
1s orbital + 3p orbital ⇒ 4 sp3 orbital (hybrid)
So,whenever we are getting sp3 orbitals, we are getting 4sp3 orbitals.
s - charcter = Number of s−orbital involved in hybridizationNumber of hybrid orbitals = 14
