Out of the following pairs of electrons, identify the pairs of electrons present in degenerate orbitals :

Options

A. `(i) n = 3, I = 2, m_(l)= -2, m_(s) = -1/2`
`(ii) n = 3, 1 = 2 m_(l)=-1, m_(s)=-1/2`
B. `(i) n = 3, I = 2, m_(l)= 1, m_(s) = +1/2`
(ii) `n = 3, 1 = 2 m_(l)=1, m_(s)=+1/2`
C. `(i) n = 4, I = 2, m_(l)= 1, m_(s) = +1/2`
(ii)` n = 3, 1 = 2 m_(l)=1, m_(s)=+1/2`
D. `(i) n = 3, I = 3, m_(l)= +2, m_(s) = +1/2`
(ii) `n = 3, 1 = 2 m_(l)=+2, m_(s)=+1/2`

Explanation

Degenerate orbitals m eans the orbitals of the sam e subshell of the sam e m ain shell, i.e., their n and I value.

so `3d_(xy)` and `3d_(yz),3d_(x^(2)-y^(2))` and `3d_(x^(2)-y^(2))` indicate pair of degenerate orbitals.
