Question

how many equivalent orbitals are involved in each of the following sets of hybrid orbitals: sp,sp2,sp3d,sp3d2

Answer 1

sp : 2 orbitals (1 from s & other from p; rearranging to give 2 orbitals of equivalent energey & value)

sp2: 3 orbitals

sp3d: 5 orbitals

sp3d2: 6 orbitals

Answer 2

    Hybrid Orbitals are the Orbitals whichon intermixing will give the set of Orbitals with equal inenergy.

          SP --- It Contains 1 S + 1P   Orbitals So it Contains two equivalentorbitals.

           SP² ---- It Contains 1 S + 2P Orbitals So it Contains three equivalentorbitals.

            SP³d   -- - It Contains 1 S+ 3 P + 1 d Orbitals So it Contains five equivalent orbitals .

             SP³d² ---- ItContains   1 S + 3 P + 2 d Orbitals So it Contains six equivalent orbitals.
