NEET Chemistry Quantum Mechanical Model MCQ Question
What is the correct sequence of orbital energy levels for the hydrogen atom?
1s < 2s = 2p < 3s = 3p = 3d
1s < 2s < 2p < 3s < 3p < 3d
1s = 2s < 2p = 3s < 3p < 3d
1s < 2p < 2s < 3p < 3s < 3d
Correct Answer
Detailed Explanation
In a hydrogen atom, the energy of orbitals increases as 1s < 2s = 2p < 3s = 3p = 3d, where orbitals with the same energy are degenerate.
