Question

The number of nodal planes in the dxy orbital is ​

Answer 1

Explanation:

Orbital labels

The number of nodal planes is equal to the value of the angular momentum quantum number, l. The 2s has one radial node and the 3s has two radial nodes.

Answer 2

The number of nodal planes in the dxy orbital is:

• The two lobes of each orbital are separated by a plane of zero electron density called nodal plane.  

• The planes perpendicular to XY plane are YZ and ZX, which are nodal planes.

• d orbital has two nodal planes.

• For f orbital Azimuthal quantum number l = 3 and the magnetic quantum number m = -3. -2, -1, 0, +1, +2, +3.
• Hence f orbitals have seven orientations in space.

• Dxy molecular orbital contains 2 nodal planes.

• Whereas dxy−dxy antibonding molecular orbital contains 3 nodal planes.
• The sum of nodal planes of dxy−dxy molecular orbital and dxy−dxy anti-bonding molecular orbital is 2+3=5.
