NEET Chemistry Quantum Mechanical Model Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Principal quantum number (n) | (i) Determines shape of orbital |
| (b) Azimuthal quantum number (l) | (ii) Determines size and energy of orbital |
| (c) Magnetic quantum number (m_l) | (iii) Determines orientation of orbital |
| (d) Orbital energy order | (iv) 1s, 2s, 2p, 3s, 3p, ... |
a-ii, b-i, c-iii, d-iv
a-iii, b-ii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
Correct Answer
Detailed Explanation
The principal quantum number (n) determines the size and energy of the orbital, the azimuthal quantum number (l) determines the shape, and the magnetic quantum number (m_l) determines the orientation. The order of orbital energies is given by the sequence 1s, 2s, 2p, 3s, 3p, as stated in the NCERT context.
