JEE Main 2025 Chemistry question
In a multielectron atom, which of the following orbitals described by three quantum numbers with have same energy in absence of electric and magnetic fields? A. n = 1, = 0, = 0 B. n = 2, = 0, = 0 C. n = 2, = 1, = 1 D. n = 3, = 2, = 1 E. n = 3, = 2, = 0 Choose the correct answer from the options given below :
Answer: (4)
Solution
D and E are both 3d orbitals, which are degenerate in absence of external fields
