Answer 1

Answer:

How many degenerate orbitals are present in d subshell three or five?

The degeneracy of d-orbitals in an atom depends on the environment in which the atom is present. In a free atom all the five d-orbitals in a subshell are degenerate. In a magnetic field, however, degeneracy is lost.

If the atom is part of a molecule, as,say , the central atom in a transition metal complex, the degeneracy of d-orbitals depends on the geometrical arrangement of ligands around the central atom. In the common cases of tetrahedral and octahedral complexes , the five d-orbitals are split into two sets t2 and e in the former and t2g and eg in the latter. The orbitals in the t2 or t2g

It has 5 degenerate orbitals.

Just in case you want to know how they are calculated -

It is calculated on the basis of QUANTUM numbers.

There are 4 quantum numbers associated with every electron in an orbitals they are

Principle quantum number(n)

Azimuthal quantum number(l)

Magnetic quantum number

Spin quantum number

To calculate number of orbitals you must know the following data

The azimuthal quantum number(l) of

S subshell is 0

p-1

d-2

f-3

The total no of orbitals equal to total no of magnetic quantum numbers a subshell can possess.

The total no of magnetic no a subshell can possess is given by total nos from -l to +l or mathematically 2l+1.

Therefore since d orbital has l=2 it has magnetic quantum nos

-2 ,-1,0,1,2 total = 5

Hence it has 5 degenerate orbitals.
