Out of the folowing paris of electorns, identify the pairs of electrons present in degenrate orbitals.

Options

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

Explanation

Degenerate orbitals means the orbitals of the same subshell of the same main shell, i.e., their n and l value
(a) i `3d_(xy)` (ii) `3d(yz)`
(b) (i) `3p_( x)` (ii) `3d_(xy)`
(c) (i) `4s` (ii) `3d_(x y)`
(d) (i) `ed_(x^(2)-y^(2)` (ii) `3d_(x^(2)-y^(2)`
Thus `3d_(xy)` and `3d_(yz):3d_(x^(2)-y^(2)` and `3d_(x^(2)-y^(2))` represent pair of degonerate orbitals.
