2025 Paper - II Chemistry
Which one of the following statements regarding hydrogen atom and other one electron species is correct ?
A
For H-atom, s orbital is dependent on the radial wave function (r) only and independent of the angular wave function (θ and φ).
B
For H-atom, s orbital is dependent on both the radial wave function (r) and the angular wave function (θ and φ).
C
For H-atom, there is no such dependence observed for s orbital; rather, the dependence starts with involvement of p orbital.
D
For H-atom, s orbital is dependent on the angular wave function (θ and φ) only and independent of the radial wave function (r).
