MCQ
The energy of an electron of $2{p_y}$ orbital is
  • A
    Greater than that of $2{p_x}$ orbital
  • B
    Less than that of $2{p_x}$ orbital
  • C
    Equal to that of $2s$ orbital
  • ✓
    Same as that of $2{p_z}$ orbital
✓

Answer

Correct option: D.
Same as that of $2{p_z}$ orbital
d
The energy of an electron depends on $( n +1)$ value and not on $m$ values.

The energy of an electron of $2 p _{ y }$ orbital is same as that of $2 p _{ x }$ and $2 p _{ z }$ orbitals.

These orbitals are degenerate.
