Match List-I with List-II:
\n| List-I | List-II | ||
|---|---|---|---|
| A | Pauli exclusion principle | I | Dual nature of matter and radiation |
| B | Hund's rule of maximum multiplicity | II | Position and momentum cannot be simultaneously measured |
| C | Heisenberg uncertainty principle | III | No two electrons in an atom can have the same set of four quantum numbers |
| D | de Broglie relationship | IV | Pairing of electrons in orbitals belongs to the same subshell takes place only when each is singly occupied |
Choose the correct answer from the options given below:
Correct answer · Option B
A-(III), B-(IV), C-(II), D-(I)
Explanation
Pauli's principle restricts quantum numbers, Hund's rule governs electron pairing after single occupancy, Heisenberg restricts position-momentum precision, and de Broglie relates wave-particle duality.
