MCQ
Degenerate atomic orbital have
  • ✓
    equal energy
  • B
    nearly equal energy
  • C
    different energy
  • D
    none of above
✓

Answer

Correct option: A.
equal energy
a
The orbitals having the same energy energy but different in orientation, are called degenerate orbitals. e.g.

$3 d$-orbital, $l=2, m=-2,-1,0,+1,+2$,

i.e. there are five different orientations represented by $d_{x y}, d_{y z}, d_{z x}, d_{x^2-y^2}$ and $d_{z^2}$.
