Match the LIST-I with LIST-II List-I Orbital List-II Radial nodes...

The number of radial nodes is given by the formula $n - l - 1$.

The number of nodal planes (angular nodes) is given by $l$.

For $2s$ orbital: $n = 2$, $l = 0$.
Radial nodes = $2 - 0 - 1 = 1$.
Nodal planes = $0$.
This matches A with IV.

For $3s$ orbital: $n = 3$, $l = 0$.
Radial nodes = $3 - 0 - 1 = 2$.
Nodal planes = $0$.
This matches B with III.

For $3p$ orbital: $n = 3$, $l = 1$.
Radial nodes = $3 - 1 - 1 = 1$.
Nodal planes = $1$.
This matches C with II.

For $4d$ orbital: $n = 4$, $l = 2$.
Radial nodes = $4 - 2 - 1 = 1$.
Nodal planes = $2$.
This matches D with I.

The correct matching is A-IV, B-III, C-II, D-I.

Answer: A-IV, B-III, C-II, D-I
