NEET Chemistry Orbitals MCQ Question
Which of the following combinations about orbitals is correct?
The energy of electrons in the s orbital is lower than that in the p orbital, and electrons in the p orbital are more tightly bound than those in the d orbital.
Electrons in the d orbital have more energy than those in the p orbital, and pairing occurs in p orbitals before they are singly occupied.
All orbitals within the same subshell have equal energy, and half-filled orbitals are less stable than fully filled orbitals.
Electrons in the same subshell must be singly occupied before pairing occurs, and the energy levels of orbitals depend on the values of n and l.
Correct Answer
Detailed Explanation
Electrons in the same subshell must be singly occupied before pairing occurs, as stated in the NCERT context, and the energy levels of orbitals indeed depend on the principal quantum number n and the azimuthal quantum number l.
