Answer 2

The pair of orbitals having the same number of nodal planes are 2p and 3p.

• At the nodal plane, the electron density is zero.
• The number of nodal planes is determined by (n-l-1).
• Here n is the principal quantum number and l is the azimuthal quantum number.
• The value of l for s is 0, p is 1, d is 2,f is 3.
• Thus 2p and 3p orbitals have the same l value.
