Question

Which of the following orbitals are degenerate?
$3d_{xy},4d_{xy},3d_{z^{2}},3d_{yz},5d_{z^{2}}$

• A. $3d_{xy},3d_{z^{2}},3d_{yz}$
• B. $4d_{xy},3d_{z^{2}},3d_{yz}$
• C. $3d_{z^{2}},3d_{yz},5d_{z^{2}}$
• D. None

Answer 1

Answer: (A)

The orbitals which belongs to same subshell and same shell are called degenerate orbitals. $\left(3 d_{xy} , 3 d_{z^{2}} , 3 d_{yz}\right)$ and $\left(4 d_{xy} , 4 d_{yz} , 4 d_{z^{2}}\right)$ are the two sets of degenerate orbitals.
